I think for some people, they aren't used to buying consoles on launch and don't release the software kinda slows down after the launch windows. It's happened with every single console ever released. I'm so glad that the Vita had such a strong launch, there is so much to play and that's not counting the PSPs (albeit limited) library. After E3 would be a better time to judge the consoles next year or so.
Yeah, that's a good point. I remember all too well the absolute abyss of no good games that the PS3 had for a huge portion of its first year. The 360 had a pretty ok first year, but it wasn't like it is now.
If you're comparing the Vita release schedule in year one to the PS3 in year 5, that's just not fair and the vita will lose every single time. Any system would. The Wii-U will lose in terms of breadth of software in its first year as well. It's just how it goes.
E3, for me, is where I decide if I should be worried about the future or not. I don't think there's any reason to be worried before then. Because like I said before, if you look at it calmly and rationally the amount of quality software this system has so early in its life (with Sound Shapes, Resistance and Gravity Daze coming in the next month...) it's above and beyond any other console release I can think of.
But, the release list falls off a cliff after june. Which is fine, for now. But that's what needs fleshing out at E3.
