I wonder where you're getting your informations from —
Scirra has been looking to hire a JS developer for several months now, meaning they are making enough with the current license system to hire more people.
It's unlikely they will change the license system (they always told they found a one-time fee to be more fair).
As for the price rising, I don't know if it will happen. Perhaps, perhaps not, there's been no word on this. Anyway if the prices were to raise again, they would clearly announce it earlier than the raise like they did before.
