It's entirely possible that the Wii will maintain and indeed gain momentum. The introduction of a successful new marketing strategy always throws things into the realm of unpredictability (see my comment on the PS1 vs SNES sales). But as I also noted, the first year or two can't really be seen as indicative of the future; the largest sales peaks of almost every single console have occurred in their first two years of their lifespan. The exceptions (PS1, PS2, DS) have all broken free of this paradigm by using a new sales model. But then, a new sales model doesn't always work (as seen with the ill-fated DreamCast, which tried desperately to capture the burgeoning online gaming community and establish itself as an online gaming stronghold).
2007 was unpredictable, and 2008 will likely be too. How much things change will depend on a great many factors, most important for Nintendo being if their "Blue Ocean" strategy really can apply to a home console as well as it did to the handheld market. The evidence suggests it can, but just the same, don't go betting too much on the future; the best-laid plans can fail, even when they've got everything going for them. I'm not saying it's likely, but I'm also not saying it's impossible.
Adenum: Another messy part of the market is when somebody does go and produce something that directly competes with your new strategy by replicating it and one-upping your effort in the process. Nintendo actually did that, in a sense, to Sega when the Genesis was biting into its share with the promise of 16-bit graphics over the NES' 8-bit visuals. And the PS2 most certainly did that to the DreamCast, literally eroding its support base away from it with ultimately false promises of a system that offered everything DC did and then some. About the only thing keeping MS and Sony from doing that at this point is a mixture of pride and the realization that they could go the way of Atari and Sega that way for releasing too much hardware in too short a time (as happened with the Genesis and its 32x and CD add-ons to be more competitive with the SNES and PS1, respectively). We shall see what happens...
