Update! I received an e-mail from Steve's brother this morning. He forwarded an e-mail that Steve's wife sent to family and friends. Here it is:
Hello everyone. After a long wait, I have some good news to share. Steve woke up this morning. I was sitting in the chair next to his bed reading, and I looked over and he was staring at me. It was a shock, obviously -- no bells, no alarms, just open eyes for the first time in a long time. That's the good news (and it's great good news). The not so good news is that he can't speak. He responds to commands by blinking his eyes, so we know, as the doctor said "that he's in there." But he can't (or at least he hasn't) speak, and he can't move his hands, arms or legs when we ask him to do that. We don't know what damage has happened -- they will now start to do a lot of tests to try to determine that. They will do an MRI very soon to see how the brain surgery has healed and to see if there is any blood remaining. His platelet count continues to be poor, and we are talking to his ITP specialists about other options. Please pray that he won't have more bleeding in his brain. I am so frustrated with his ITP. I know what Steve would say -- "hey, ITP is easy, try cancer if you want to feel sorry for yourself." For now, I guess, he's awake, it appears that he survived the surgery, he's breathing on his own, and for all of that I am very happy. Now we hope and pray that he hasn't lost his memories.
The only down side to this count is that the last treatment I had was just 3 weeks ago. 
My next count is at the end of Feb. Hopefully there won't be much change!
