Extremely doubtful.
For fantasy gaming, I already have D&D (2nd, 3rd and 3.5 editions, plus PDFs of the Rules Cyclopedia and the 1st Edition hardbacks), WFRP, Iron Heroes and Exalted (1st Ed). That being the case, I really don't need a new system, especially a rules-heavy system - I've long since passed the point where I'm interested in spending days learning a game system, unless it blows me away.
I'll make an exception for a new edition of D&D, since it represents the baseline in gaming, and so is useful to know for moving between groups. Otherwise, though, I'm not interested in new fantasy games.
