-either have 5.5
-or a new x-pac in 6 months
-or patch 5.4 for 10 months
-or a combination.
Even if patch 5.4 is "only" out for 6 month, I guess people will cry. 5.3 was released mid-may..so we hardly had 4 months of that - on the other hand, ToT was released early in march, so one can claim the last raid tier lasted 6 months.
Vaguely pointing to March 2014 for the next x-pac?
