Just tried it and no good.
Installed Vita last night and nothing worked like everyone else. Then installed PS3 version, it worked, I played it, I sucked, I enjoyed my time. Tried to upload save to cloud for cross-save, took over 5 minutes so I killed it. After reading the above, tried to launch already installed Vita version, no good. Then deleted that one, and redownloaded, still no good.
I do see there is a new version that I can add to my cart in the store now (as MildPeteGeoff mentioned earlier), PS3 version shows free, Vita version shows price. When I try to check out w/ the PS3 version, I get an error and can't complete the process.
tl;dr: Shit still broke.
