I think its all the political and lawsuit threats going around, Sony is determined to keep us under the thumb. But all this means is, that devs just aren't going public with their findings, not that they aren't working on it. I believe oneday soon someone will come out of no where and have 101 new things in their pocket they have been building up for a grand release. Then all the people who were saying the scene is dead will be the first to scream they knew it all along...
