Earlier today, a tweet posted up by publisher 2K Games stated that the PlayStation Vita version of Borderlands 2 would be getting a launch date of March 18th, 2014. It seems that someone jumped the gun a little as they have retracted that in a follow-up tweet.
We can't show you the original tweet as it has been removed from twitter, but here is the latest one stating the error:
We apologise for a tweet about a release date for Borderlands 2 on Vita which was posted in error. The release date mentioned is incorrect.— 2K United Kingdom (@2K_UK) January 21, 2014
There, of course, is no indication if the date was actually wrong (although they did say it was incorrect) or if someone just tossed it out before they were ready, so we'll just have to wait and see what happens.
