I love all the righteous anger in this thread. Yes, the press conference was roughly 1.5 hours too long and short on details, and there wasn't enough shown to make me a day one purchaser, but nothing pissed me off either (until just a moment ago).
Sony confirmed the PS4 will play used games, and the streaming is only for BC games, not the new stuff on the system. BC is nice, but it's not a make or break for a game system. The system does include the ability to play games as they download, which is nifty. I don't care much either way about the sharing/social features, and it's a new system with faster processor/better graphics, so woohoo, I guess.
What does tick me off is today's confirmation that PSN purchases won't transfer over. Unless they're planning to offer some sort of conversion credit (ha), then I'm not going to repurchase things just so I can stream them on the new console.
Jam it back in, in the dark.
