Blood Reaper, they won't disappear. Not sure where the source is but it's been confirmed by dear old Toddie himself that the number of dragons is infinite and all the souls brought back by Alduin as dragons will stay in Skyrim til they die. And Oblivion gates weren't infinite, if you use tmm 1 in the console on the pc you can see that all of them have particular locations.
