In the end, Jimmy Danger said it right. Xbox has grown as a brand greatly since last gen with install base, 3rd party support, and profitability. The Playstation brand has been on decline to put it lightly. But the Wii is the overall winner.
I personally consider 360 being 2nd or the #1 HD console in the time period where all 3 consoles were the most current and relevant a major victory and milestone. Thats 7 years of beating the former #1 brand in gaming.
PS3 can have all the longevity it wants, and the fans have a right to celebrate any milestone it gets. But if all 3 next gen consoles are out, I personally would have moved on and couldnt care less what happens to the older consoles. No matter how you slice it, the spotlight is taken off when all 3 next consoles release.
So as I said before, to celebrate taking 2nd, after 7 years, after the next gen fully releases, all the while with Wii being #1 and the only winner to be remembered by history, to celebrate 2nd is to celebrate lowering the bar. With the OP, it wouldnt matter a damn bit.
