No question: Take-Two lurves their BioShock baby. In an announcement today, the publisher revealed that, to date, BioShock has shipped over 2.2 million units across both the Xbox 360 and Games for Windows platforms. Not too shabby, eh?

It's clear that with this news, Take-Two's gearing up for BioShock mania. Combine strong sales with the recent announcement of BioShock on PS3, news of the Verbinski-directed BioShock film, and the inevitable BioShock 2 announcement from 2K Marin, and we're on the cusp of the next big franchise in gaming. Good thing or bad thing?
