I read somewhere, maybe Matt Brown, that the one year delay (according to the initial plans it was supposed to be released last summer) was caused by the fact that they wanted to start from scratch without taking Madden engine.
If you want real and verified updates on this matter you gotta follow Matt Brown on Twitter, he has connections into EA.
Gator Dave is a fraud (shocking, I know) and has been dragged all over the internet for his report.
