Tyson Gentry met with the media a few days back, leading to a variety of articles on his current situation. There's the AP article, the O-Zone article, and the Dispatch article, among others. Buckeye Commentary also has a nice post up about his status.
They all say pretty much the same thing: he's getting feeling back pretty much everywhere, he has some use of his arms, but he still can't walk. He and his family are pretty upbeat about the possibility of him walking again, though. In fact, every article made mention of how positive he's been through it all, which is very important, I think. I don't know much about recovering from these types of injuries, but I do know that he has a lot of work ahead of him before he'll be able to walk again, and a good attitude will make that much easier.
I hope I'll be at the Horshoe the day he walks onto the field. I'd pay more to be at that game than any Michigan game.
