I am actually predicting Nintendo to do much much better next generation, but I still say they will be considered number 2 or 3 depending...but it will be a tie.
I really don't see Sony doing that great next generation. Microsoft is being extremely aggressive in marketing and delivering a unique product with Xbox 2. I thought the whole HD generation was stupid...but I also think their online plan is brilliance. Pushing a community and striving to create the perfect online experience will make the Xbox 2 the system to own for online gaming. Period. That alone will help boost Xbox above PS3s position.
On the PS3. I haven't really heard, or read anything spectacular about it. The rumors suggest it will use Blue-Ray disk technology for incredible storage and viewing high defination movies. Well, I don't see the market really getting behind that as much as DVD technology. It won't be an issue. There isn't a large outcry for better home movie technology yet.
I also think technology isn't advancing as fast as we think it is. Microsoft can easily design a system that will release early and still be close to equal to the competition in hardware specs. Though reality is that won't really matter anyway.
Now, when it comes to the Revolution, Nintendo has an underground hype going on. Their is an anticipation to see something great from Nintendo, and see a second coming. See everyone respects Nintendo as a company, and knows how great they are. Most people believe Nintendo will have a second coming and a rebirth. Anything to shows innovation and creativity by Nintendo in the hardware will be embraced. Just look at the success of the DS, and the excitement over the Revolution. I think that is pretty good proof.
If Nintendo delivers half of what its promising then Nintendo will gain back its marketshare to number 2 easy. If they totally blow everyone's mind and have the games to support it, then Nintendo will easily gain 1 place.
The more I think about Revolution, the more I begin to believe Nintendo isn't necessarly talking about just a new controller...but a whole new concept and understanding in gaming for us, but mostly for Nintendo. I think Nintendo's revolution may actually be in the technology and how they use it to go online. If this is the case, Nintendo may even out do Microsoft...but again they will have to beat that perception that MS knows online.
Those are just a few of my thoughts.
