While I think it's almost inevitable that CA will produce a Rome follow-up, probably based on the Empire engine, I very much doubt that they will ever make a product that won't benefit from the attention of teams such as RTR, EB, RS etc. Such a game would just not be universally marketable.
CA will always be obliged to adopt a slightly "Hollywoodish" approach to historical accuracy, to ensure maximum appeal to the maximum number of players. And, to be honest, I don't think it really matters, due to the symbiotic relationship that seemingly exists between CA's basic product and the modding teams.
CA produce a cracking generic game, which the modders then fine tune to suit their particular tastes. It was, and will ever be. thus.
I just hope they sort out some of the wishy washy troop movements of Med II before their next game.
