if by "DOTA FPS" you mean their new MOBA Deadlock, AFAIK it's not related to DOTA in any way.

Other than being developed by the same guy, IceFrog, that originally developed (the final versions of) DotA. That's been the community "common knowledge" for a good while at least, I don't know if it was ever officially confirmed.

Oh, is Deadlock by IceFrog too? I've been keeping on its development but hadn't heard that.

Thanks. Yes, I mixed up the acronyms.
