I strongly disagree. I think consumers and developers will care, in the sense that it's essentially free advertising for the next console. Tomorrow will be a huge BF4 reveal, with coming to PS4 splashed there with no mention of the Nextbox, that's free advertising and hype for the PS4 and less coverage for Nextbox.
And how have you come to the conclusion that the 360 is leading? America? Sure. Europe and Japan, no. PS3 as far as I have read, has overtaken the 360 in global sales, and sells more worldwide on a monthly basis. based on EA's figures, the PS3, despite having less software sales, actually makes EA more revenue than the 360 too, due to it's Euro dominance (where games are costlier and reflected in increased revenue).
