If the 360 drops to 199/299 before christmas then there is no way the ps3 will ever catch it-unless the ps3 also drops to that same price point.
the wii is interesting, it breaks the "more power" tradition from console to console- being equivulant in power to the ps2/xbox of last generation, yet it's innovation and price point= massive sales.
i DO forsee in the future -around 2010range- the HD version of the Wii -at 250....
