Okay, I'm done lurking...been a long time now. I need to say that there are some pretty talented and imaginative folks here!
I can see the comic style costume coming to the Nolanverse due to a couple of reasons:
1. Nolan has, to date, incorporated many aspects of Batman lore into his films. He has paid tribute to many scenes of Burton movies and probably done more than I even know(not that I am a Guru by any stretch) in that regard. I think He is going for the complete and thorough Batman developmental experience(IMO).
2. The progression of Batman from Begins(where he needed to be seen and remembered, described, embelished, etc) is critical to becoming a legend, to TDK where he is established and needs to be able to live up to the legend(protected, yet fast and practical), to BB3 where he will be on the lam and need to conduct his Bat-business from a stance of secrecy and doesn't want to be seen as much, and will probably engage in less combat and more detective work due to his status being "wanted".*
* I am aware of that being one of the largest run-on sentances ever

Just my thoughts....the AA game and the success of the recent movies are intertwined. I can see the BB3 movie following the AA game premise loosely, and visually as well. It would complete the transformation and from there could continue....or wrap up for Bruce. At least the Nolan cycle could be considered complete. I believe the BB3 suit will pay some homage to the comic style, while remaining protective, it could utilize the big cape for hiding and protection. I think something like the AA suit would provide this.

Thanks for all the pictures and manips...you people who do that rock!
