I find it odd, though, that PSV-compatible PS1 titles will be coming out in a trickle. For a moment, I interpreted that to mean you'll have to rebuy them--but I think that wouldn't make sense for a device that already uses the PS Store.
It does bring up a question I should have wondered about earlier, though: how is it that PSP games have been getting "turned on" for the PSV? Prior to it happening, I had assumed that it was going to be via PSV firmware updates, but none of you PSV owners have talked about such things happening. So why is it that games which previously wouldn't work on the PSV suddenly do work, even games which you could transfer to the PSV previously but couldn't actually run? Are the games themselves being patched somehow, with PSV-specific versions (which I guess would mean that a download to a PS3 would have to have pieces of both PSP normal and PSV-compatible versions)?
Anyway, the press conference was, for me, unexpectedly devoid of any really big, upheaval-type surprises. Certainly, the JK Rowling augmented-reality PS3 book revelation was a surprise, and it looks like it could actually be pretty good for Potter fans, but it's not, as far as I could gauge, a game-changer. There's a Crystal White PSV coming, bundled with the AC3L game, but no PS3+PSV bundle like some were expecting. No price drops for anything, either. A minor surprise: PS Suite has been renamed PS Mobile, with HTC on board with new devices.
Something I'd like to learn more about: during the prerecorded walkthrough of Sony's E3 "booth," there was a very visible (hot pink) Hatsune Miku sign in the background of the closing shot. Is the presumably Japan-exclusive Miku game playable at the booth or something? Has that happened before, a Japan-only game being playable at an E3? Or is this a sign that Sega may actually be bringing the game overseas?
Final thought: the conference's live UStream seemed to peak just shy of 83,000 concurrent viewers, during the The Last of Us demo.
