Last time we saw him (at the end of Descent Part II), it was said that he would be disassembled and stored at, I'm guessing, the Daystrom Institute (probably in the same row of drawers that B-4 is stored in).
All it takes is for some bad guy to break in there and reassemble him. As to why they didn't just outright incinerate him so that something like this would never happen, I'll never know. But maybe I'm answering my own question since he can easily be brought back since he wasn't incinerated.
I know that Brent would said he would never want to return as Data since Data is now dead both physically and "spiritually" but who knows, maybe he wouldn't mind returning as Lore to make Picard's life difficult again. Actors love playing bad guys!
