Should Nintendo or Microsoft adopt Blu-ray for their next console?

[Blazkowicz]

I actually like this idea, that way when you take the game to a friends house it's not some unpatched or 'wrong' version etc.

As for the disc based systems... Since HD-DVD is considered a dead format, would it be 'dead' enough to say be used as a proprietry format by MS or Nintendo?

It doesn't make sense for the industries to keep producing a dead format, there's still the option of BRD without movie player royalties, DRM makes the format proprietary.

Online only is a long way away. Why, coz the entire world doesnt have ISPs with good bandwidth/cost ratios.

Download speed is one thing, actual month data cap vs cost is a whole other problem.

Simpy put, the market isnt big enough for it yet for devs to consider a profitiable medium. (compared to the market size of "people buying discs". You have to think outiside US and Europe.

agreed. you would cut off people in unlucky nations or areas as well as islands (such as Australia and NZ)

that would put an end to the whole walking in a store and buying games, too. I remember getting almost all console games as Xmas or birthday present (or bros's present). The other ones were lent or bought used.
So with digital distribution only you would piss off mom, kids and the game publishers, who will never accept it. Stores would have few incentive selling that console when the other ones bring game revenues.
