I looked for EA's announcement regarding their new deal... and this guy is right - no new mention of "exclusivity" which one would think would be frequently boasted by EA if they had secured it again... there is also something about Peter Moore being pressured into what exactly their agreement with the NFL is and the conversation going nowhere ...
I can understand if 2K is able to make a game now, why they wouldn't have announced it up to this point. (For those of you thinking this rumor is fake because nothing has been said)
EA's announcement of their deal with the NFL came at the very end of January - meaning 2K would have around 7 months to secure contracts with the NFL and NFLPA, all the while getting the band back together, and of course making a new game from scratch. In other words... there won't be a game until 2015. 2K knows their fans are loyal and have been looking forward to this for a long time, so in the interest of remaining interesting, they aren't going to leak online one day that "Hey guys, we're back! See you in a year and a half!"
If I were them, I would do what they are (hopefully) going to do and blow it up at e3.
