1: Yes. Ambrosia have stated that they wish to publish a series of Coldstone games, similar to AD&D; modules. I assume they would publish only the ones that they think are the best, for economic reasons if nothing else.
2: You can submit a developer application through Ambrosia's (url="http://"http://www.AmbrosiaSW.com/support/techworks/")Techworks(/url) system, and if they accept it I suppose they can publish your game.
3: Yes, with a registered version of Coldstone you may release any game you make independantly as shareware. Commercialware requires a license.
4: Perhaps, perhaps not. Dee Brown has stated that he'd like to do a 2.0 version, but there are numerous factors involved. Currently, there are no plans to release another version of Coldstone, but if it proves popular enough, then, well, who knows?
