It depends on how you look at it.
Microsoft made an announcement (FFXIII) that prevents thousands, if not tens or hundreds of thousands of Xbox 360 owners not need a PS3, as MGS4 is the ONLY 3rd party exclusive left that is worth a care.
Nintendo showed the 1:1 that has tons of potential, but it looks like Nintendo didn't bother showing anythinng that will make it cool for core users. However, Wii Music + GTA + Wii Sports Resort (w/ WMP) will sell great, and make Nintendo hundreds of millions of dollars.
Sony announced games that we knew were going to come out, sans MAG. Who is MAG goin to cater to? The existing PS3 fanbase. And thats the issue. Sure, a Sony fan might say (and we've seen it) "OMG, SONY FOR TEH WINZ" and will buy 2-3 more games
So MS keeps a larger userbase for itself, Nintendo takes a larger casual userbase, and opens up great core possibilities with WMP and a viable strategy for distribution via Wii Sports Resort, and Sony......Sells a few more games?
Back from the dead, I'm afraid.
