Wasn't Sony not supposed to reveal too much at E3s anymore? I mean, to a certain extent they are obligated to have a presence at the show, but I thought they were going to save more of their heavy hitters for other events like TGS.
I don't know what to make of Vita other than it's a wonderful piece of hardware that doesn't have a whole lot of software. It seems like a typical Sony product--brilliant, quality tech that's overly proprietary, priced too high, and lacking in proper content support.
I guess at the moment, they are stuck with Vita as an "accessory" to PS3. Granted, that may have been the goal all along, but $250-$400 is as much or more than the PS3 itself. It's a tough sell right now without the right titles to support it.
I'm still pretty happy with the system though. It's a nice little media player and I mostly have fighting games on it anyways.
