2008 will not be the year of either the PS3 or the XBox 360!
The price of the XBox 360 and PS3 will remain above the price most people are willing to spend on a videogame system for most of the year, third party exclusive games for both platforms will become sparse, and key games will continue seeing delays or underperforming.
The Wii will (likely) see twice as many third party games released this year, and three or four times as many quality third party exclusive games because of the success of the Wii in 2007; whereas the Wii mostly saw quick ports of PS2 games in 2007, in 2008 the Wii will see a lot more games that were developed by better development teams with larger budgets and longer development cycles. Nintendo's plans are (mostly) unknown, but the success of Wii Fit in Japan will probably translate to North America and Europe, Mario Kart and Super Smash Bros. have massive crossover appeal and will sell (amazingly) well, and we're likely going to see the return of several series (as well as new series) for the end of 2008. If Nintendo starts to see a steady supply above demand they are in a far better position to reduce the price of the Wii (or offer solid bundles) to encourage further sales; they could (potentially) sell a Wii, Wii Sports, 2 Controllers, 2 Nunchucks and a game of your choice for $200 with minimal losses.
