No, not really. We knew from the first webcast, two months ago, that OL did not receive an overhaul, just tuning and tweaking.
We do feel confident, that a former pro OL, is working in that area for now and in the future.
And you are correct in your expectations. I plan on supporting 13 for the efforts they made going for it all with rtp, and with the hopes of them working on OL/DL for Madden 14.
