Yes it has been indicated so far that more then one planet is under attack and the futher in the game you get, the worse the situation gets.

We know the other species seem to be having internal issues that Shepard has to deal with. Bioware has so far shown us: Sur'Kesh has become embrolied due to the genophage issue, the transport of the fertile female to the krogan has led to an attack upon the planet by Cerberus.

A geth controlled world is home to a Reaper base, which Shepard discovers is really an actual Reaper.

The krogan on Tukanka have come under attack at some point, as a battle has been mentioned against a Reaper which ends when a tussle between the Reaper and a Thresher Maw.
