Just got this email literally seconds ago:
We are pleased to announce the official release date for episode 3 of Pioneer One: Monday, March 28th. An official release date for episode 4 will be announced soon, but we plan to release it within weeks of 3.
We also have a start date for production on episodes 5 and 6: May 5. Whatever money we raise between now and then is what we'll have to make those episodes, so we're hoping 3 and 4 will get us some new fans who want to see more!
