Just saw this on the PlayStation Blog:
Become a PSM Publisher for Free
Developer registration is usually $99 but it's free starting today until September 2, 2013.
Registering as a PSM developer lets you release apps and games for the PlayStation Mobile platform that currently runs on the PS Vita and several Android smartphones. Notably, Super Crate Box is on PSM and I've played it on my Vita (works great thanks to the buttons).
Maybe Scirra will update C2 to export to PSM before the free period is up? :)
