EPTI would be very surprised if it broke HoTS sales as i haven't seen any hype anywhere else but on this forum.
No one is interested in this expansion at all outside of TeamLiquid and after getting burned by HoTS there will be a lot of people like myself who will not be purchasing it at all.
HoTS was a step backwards from WoL and after seeing some of the streams LoTV looks to be more of the same. Gimmick units designed to frustrate the player base with all ins and cheese, more air units that bypass terrain and units that still have massive ranges.
Once the initial hype dies down, the decline in viewer base will continue even lower than it is now. SC2 rarely makes the top 8 games stream these days and in fact Broodwar surpasses it on most days
