At this point in time I don't think you can make the assumption about how any console will perform in the next generation ...
Right now between the massive success of the Nintendo DS and Wii I think that it is fairly safe to assume that no matter what Nintendo produces in the next generation third party publishers will give them full support immediately; on top of this, people are probably far more likely to buy the same make of console from one generation to the next if there is no real reason to change manufacturers. These two factors give Nintendo the same advantage that Sony had heading into this generation.
The two things that will determine who is the most successful console in the next generation is whether the console manufacturers learned from their (and eachother's) mistakes, and whether the console manufacturers learned from Nintendo's success; if Sony (to pick a company) thinks that the reason the Wii is popular is that it is a low powered inexpesive system with simple games, and ignores the value of inovation in user interface, it is quite possible that they will produce hardware that is so unpopular that it rivals the nGage in mockability.
