I'm going to stick my neck out and make some bold predictions. Check back a few years later to see if they are correct.
1) The format war between HD-DVD and Blue-ray ends next year with HD-DVD fading out. By gambling their whole console business on Blue-ray, PS3 provides a ready market for Blue-ray content which has a positive feedback loop with the amount of content available for it.
You think companies that invest billions of dollars in HD-DVD is going to let it die in 2 or 3 years. BetaMax was introduced in 1975 and lasted well into the 80s. In fact, the last betamax player was produced in 2002.
2) Blue-ray, once dominant, becomes an important feature that adds value to PS3.
Dominant over what? HD-DVD? Once this HD format war is over, the winner has to take on DVD. DVD is not going to give up its dominance within the next couple of years especially when the new HD format requires the consumer to upgrade the player as well as their TV. Its going to take years for HDTVs to even outnumber SDTVs in the market.
3) Wii sales will stall within 2-3 years and Nintendo will release a new console with comparable processing power with Xbox 360 and PS3 in 2010.
Even if your guess is true, sales for a market leader console typically peak at about 3 or 4 years (PSone at 4, PS2 at 3). The Wii has the added benefit launching in all major regions within a one month window. If the Wii continues to outpace the PS2 (like its currently doing) for the next 3 years it will be north of 50+ million before it hits a "stall".
4) In the next few years, Wii owners will be looking to buy a graphically more impressive console, at a time when PS3's technical advantage over Xbox 360 is beginning to show as developers get to grips with the Cell.
I can understand why this general belief (graphics is king) persists but it does so in the face of strong evidence to the contrary. Consoles and its game sales trump PC vcards and its game sales. The PS2 console and game sales trump the Xbox/GC consoles and games sales. The highest selling franchise of the last decade (GTA) is probably one of the ugliest (in terms of visual quality) top franchises over the last generation. You can generally sell more games with a blockbuster movie tie ins then showing a title with just high quality graphics. The hottest selling console this generation is graphically the weakest.
5) Installed base of PS3 overtake Xbox 360 by 2010.
The PS3 has to turn around within the next 6 months for that to happen.
6) Neither MS nor Sony have a strong urge to release a new console even though Nintendo is selling one. They'll both make money and sit on their current hardware until 2013-14
And they will find themselves playing second and third fiddle to Nintendo.
7) Nintendo completely distinguish their consoles as "something else" in this business and no longer release new consoles in any degree of synchrony with MS or Sony. In other words, there will be clearly different cycles for different segments of the market.
Since all console garner most of their sales from the same segment (general or casual), I doubt that Nintendo will break away from Sony or MS in terms of release cycle.
8) Phantom will launch in 2016 to great success.
Nope, It will drop the same year as Duke Nukem Forever
