The Data thing is my biggest question. We don't know for sure that's Data...it could be B-4. If it is Data, then they have to explain how Data has come back from being blasted to bits. This is of course assuming it's canon, which I hope it is. Anything canonizing more of the life of Spock is great in my book. Maybe Pardek will make an appearance. Heck, maybe even Scotty and McCoy.
So how do we find out for sure if this is canon?
