Mortal Kombat X - Did the release date change?

I pre-ordered it for PS3 in-store at Best Buy last week and didn't notice that the release date listed on the receipt is 12/31/15 until the cashier gave me the instructions on picking it up. On Gamestop.com and Target.com it's still listed for 4/14/15 and on Amazon and Walmart.com it's shows the relese date as  6/30/15.

Did WB change the release date and not all of the retailers have changed it yet? And if the date has changed and BB corrects it should I cancel my current pre-order and start over?

Last gen versions I think I read were delayed until 6/30.

Yep. Older consoles got pushed back.

Last gen is being ported by High Voltage and they seems to have run into problems so it got pushed back on PS3/360. PS4/XBO/PC is still scheduled for 4/14.

Well that's I get for not keeping up with video gaming news. Not going to complain or cry foul about the change in release date though. I'll keep checking BB.com for the updated release date and reset my in-store pre-order when it does. Thanks for the info everyone.
