I don't think so. Forums everybody has. Content, humm... Don't know, IPS wants to release it anyway this year. We're on Nov 21! Don't expect a final release to happen after Dec 10. They don't want to spend Christmas and New Year with Tracker exploding in bugs. A big release like that always has issues on conversion, etc. Anyway, that's my opinion... only IPS knows what will happen.
Probably some change in framework would be required. Not sure if only Content will handle that. I mean, if you want that only blocks from Content appears on left side, that I think it will work. When I said, I meant the whole thing (hooks, widgets, etc).
