Perhaps a tad.
Keep in mind the last update was the largest to date not counting AH2's first release itself.
It was the exception to the rule, not the new rule (not yet). You can probably only expect a couple of planes. Faster, smaller updates, perhaps? (that would be nice! Steady progress instead of bursts, right?)
EDIT: One word: Lancaster. Buggiest bomber flight model in the game, soaks up damage from 30mm rounds with no effect, won't catch fire. Fix this, bring it to the level of the other bombers, where it's reasonable to shoot it down.
