Assuming you have maintained a good airlock/sanitation, the beer should be fine -- if not fantastic -- depending on the style. I've bulk conditioned a dopplebock and a wee heavy for nearly that long, and I added champagne yeast (1/2 a packet/ 5 gal. batch, it beleieve) along with the priming sugar to ensure good carbonation. Those puppies still took 6 weeks to carb because they were big beers.
I would add the champagne yeast just to be sure your bottles will carbonate. As I recall, champagne yeast is used for 2 reasons: it can stand a high alcohol environment and it will not add/alter the flavor of your brew.
