I think Sony's business strategy was more appealing to both CE's and the movie studios.
As I mentioned though, a number of those CE manufacturers were on BD in the first place because they had IP stakes in the format. Philips and Panasonic weren't there casually, that's for sure, and Samsung and LG went rogue after they saw there was money to be made playing the middle.
I treat the agendas of the movie studios and the CE manufacturers as wholly different in this regard. For the movie studios, these were the key criteria: CE support, guarantee of replication cost/volume, and speed of transition.
Before the format war ever got underway, Sony didn't bring forth an offer so much as a threat, that threat essentially being that through their internal studios and inclusion inside PS3, supporting HD DVD
without a war was simply not an option for anyone. At best, HD DVD would win a war of attrition, with Sony ensuring so long as they deemed fit that both a software catalog and machines able to play the format would be available. In addition, the size advantage was important enough for Disney, and the BD+ inclusion important enough for Fox, that both went exclusive to Blu-ray. Further to this, Sony was willing to absorb the high cost of early gen BD replication themselves and partially subsidize the cost of the discs pressed for their partners at Sony DADC. If Sony didn't have such absolute control over all aspects of the BD supply chain, I wonder if it could have been pulled off; of course their having their toes in all of it is what made it so important to win.
Paramount and Universal were always two studios that favored HD DVD for the economies surrounding the format - the reasonable assurance was there that replication would be cheap, and volume needs not a problem. After all, a simple $10K investment to turn a DVD line into HD DVD, right? Paramount was convinced to go dual-format though, and Warner went that route as well. Frankly before the start of the war Warner's move blew me away, and I think myself and many others thought it would be over before it ever started - afterall if Warner, which actually had an IP interest in HD DVD winning, was willing to consider BD's position... then certainly the future had been pre-determined.
Well, HD DVD managed to get Universal to go exclusive, and the stage for confrontation was set afterall. Not only that but Warner seemed to increasingly play its favor to HD DVD as time went on, and of course Paramount had it made worth its while to give up on the BD gambit. Where HD DVD was a clear underdog at the outset, things actually started to look headed towards a long grind as the winter of '07 approached. And the thinking was that such a situation would ultimately benefit HD DVD over the long haul, as the BDA alliance increasingly had its various interests pulled in different directions.
But, luckily Warner - who had always had resolution near the top of its agenda - found that stalemate wasn't anything that would actually benefit the studios/consumer, and decided to side with BD due to the active user base and partner ecosystem that was in place (and supposed additional incentives). Not that if they had gone HD DVD - as many thought they might - it would have been any more of a surprise, that being how intense things were getting at that time. But I think Warner realized that if they
did go to HD DVD, that wouldn't lock the war so much as simply help (though immensely) HD DVD. The BDA studios would still keep fighting. And so in that context, if Warner truly wanted to end the war with any high degree of assurance, there was only one certain choice.

I don't think there's any dispute here that the PS3 is what ended the format war; in my opinion it is the definitive device of this entire optical generation. Indeed I think it's probably the best mass consumer A/V device of all time. When I personally refer to 'the mainstream' consumers and such in this thread, and the consider the appeal/substitution of a PS3-derived standalone, I certainly am not talking about myself - I had a PS3 on launch day, had always wanted BD integration, and was a supporter of the format from day one for reasons that existed completely outside of its console tie-ins. But at the same time, when I was hoping that BD inclusion would ultimately make it in, I was also expecting a launch price of roughly $450. When $500/600 was announced, I found I could certainly cope, but a lot of folk that were in that mainstream segment were very much turned off.
The discussion here now I think just comes in the form of reflection on the price paid to use PS3 as a vector, both in immediate costs and in the opportunity costs of the gaming division's market position... and in wondering whether Sony might have had other means of achieving its goals without having been bruised as such. It's really just a thought experiment of sorts, because honestly I don't think history will ever forget the PS3's role in determining the outcome.
PS - No doubt an entire thread concerning MS' own position in this war could be had.
