2K's UK Twitter account has tweeted out a very mysterious BioShock -related image.

Oooo, what COULD this mean?! pic.twitter.com/P93Nl643SU

The image is an in-game advertisement for Eve's Garden, an "exotic dancing venue" (ha) from Fort Frolic in the original BioShock. It was tweeted out twice by the account, accompanied by the teases "discuss" and "Oooo, what COULD this mean?!"Interestingly, nothing of the sort has been tweeted out from 2K's general account, suggesting that whatever is in the works could be a regional promotion.Otherwise, we don't really have any other big theories here. BioShock Vita is basically a lost cause at this point, and while we know that 2K is still exploring the BioShock universe since Irrational disbanded, we've heard no rumblings since the publisher assured us the franchise wasn't dead back in February.Sound out on your hopes and dreams for the future of BioShock below.
