You could be correct, but you also have to remember the Madden will benefit from a LARGER development cycle. The FIFA Vita devs already went on record stating they basically ported FIFA 12 over because they were (at the time) working on completing FIFA 13 and didn't have the time to import the feaures and keep its launch window in tact. I don't think this will be the case with Madden, we should get as close to Madden 13 on consoles as possible. Albeit, Madden 12 wouldn't be a HORRIBLE option if most of the gameplay is tuned correctly.
My concern is that, we will get the Madden 05 (PSP) like engine as opposed to a new one.
