I guess the question is did Mobile phone games ever round up a hardcore fan base? I think the answer is no. I think mobile games are so restricted due to it's technical limitations, that most realize they can play games on another handheld system, that's made purely for games, with less limitations, making for better animation, and graphics. People understand that a tiny cell phone can't hold all that info, so games are mostly casual on it, in my opinion. Not to mention, no one has done much ground breaking in terms of game play and whatnot, nor has a company gained mega status as "the best" game developer with cell phone games(save for better graphics, with better hardware and software on the cellphone). Just another outlet to play the game, that's all. I believe they will remain casual, but not go out of fashion...hope this made any sort of sense.
