I don't know about plans, but I'd like more to play a game that you devs consider finished and then see it receive 1-2-3-4 big updates over time than to play an alpha that is not even near finished. I'm saying this even thought I know I'll take G2 probably at launch since I love G1 just so much and the premises seen in this content seems fantastic and everything and more I'd ever want for a sequel of such an amazing game.
Keep up the good work, Obsidian, you're doing great!
