Indeed this is an interesting update. I have come across a Midway Arcade Treasures 2 Information 2 page sheet and it reveals that the website for Midway Arcade Treasures 2 is
http://www.midwayarcade.com. Apart from this information the sheet details the games that will be in the Midway Arcade Treasures 2 collection, platforms and systems. However as it Lists Mortal Kombat 2 and Mortal Kombat 3 there is no mention of Mortal Kombat 1. We have already learnt that with the Collectros Edition of MK:Deception they will be including an "arcade perfect" version of Mortal Kombat 1 maybe this will be the only way to obtain the original classic? Remember this is still an early information sheet, nothing is 100% confirmed here. I have sent an e-mail to my Midway contacts to see what I can find out. I have also posted some images from the information sheet including a shot of what could be the final cover art for Midway Arcade Treasures 2 (notice they also changed the logo from blue to green). (I had to cut off the 2nd page as some of the information on it is sensitive) Remember where you heard it first, at Total Mortal Kombat!
