As a company, who actually did increase its staff a few years ago, it is no surprise they look for growth in products they're able able to offer when an opportunity arises.
From what I gather, this potential product sorta, kinda, fell in their lap with the activities of one of their relative new developers.
I wouldn't be surprised, that a full subscription model to C3 will also include the animator, and for those merely looking to animate small videos, a lesser subscription model dedicated to the animator will see life soon.
For those worried this will eat up scirra's development time, the core of the app is derived from CS3, the amount of "extra" time which will be consumed should be minimal.
For those desiring other elements be build first .... make the suggestion more popular, and start moving people to vote/talk/discuss/request it. Scirra is not blind, they see and hear, and base their roadmap on a lot of that.
As is in life, you can't please everybody.
