Didn't some of Sony europe guys say in some interview that "PS3 will go underground until E3 2006" or something like that.
Then I wouldn't be surprised if any true new info wouldn't be released before that.
Also, by promoting the PS3 heavily this year, before the xbox360 launches, they'd be at the same time promoting the xbox360 in a sense.
I mean by promoting the PS3,even though it won't be available until next spring, after xb360, they'll
build awareness and hype of next gen consoles
in general and at the same time make people think they'll
need a next gen console now.
But as the only next gen console available soon will be xb360, I'm sure many people who are not that "true to platform" will think "Ok, I'll by a next gen console then, now what's available.... hmmmm.. there's only xbox360.. I'll buy that as the next gen and HD era is so "now" and talked by everybody, it'll be like next gen playstation!"
They of course could counter that phenomenom by putting the PS3 hype against xbox360 sales campaigns, making people think "ok, I'll wait for the PS3 then instead of buying the xbox360 this christmas", but I guess they'll just let the xbox360 have it's time in limelight
