I think these debates on power/graphics will continue until E3 next year....once Nintendo show off the next wave of first party titles then we will see what the machine is capable of
They're kind of superfluous right now because there's no point of reference. We all expect Sony and Microsoft to launch more powerful consoles, but we don't know how much more. We don't know how much that will matter. It's more up to 3rd parties to make games for it and consumers to accept the reality of buying new hardware. In both cases, they could just decide to stick with what they have. The same could be said of Wii U. However, 3rd parties are mostly porting and Nintendo fans will, for the most part, buy an entire console just for Mario, Zelda etc. It's a different fan culture.
Its weird but yeah since the cube i've only ever bought nintendo consoles for the exclusives....always used my xbox for the 3rd party software
I find it hard to imagine the jump next gen will be as massive as previous gens

E3 will be very interesting next year
