We already know the Galaxy Note II is headed to all of America's "big four" carriers with Exynos and LTE (well, LTE on 3 out of 4) in tow. What we don't know is when. Samsung promised "before the holidays," but that's a pretty large window. It seems likely that window is about to close - next month.
Samsung has announced an event to be held on October 24th in NYC, and the invitation makes it quite obvious what the topic of discussion will be.
