Honestly, if they charge >$180 I can see it splitting the users (the same ones that are generating all the excitement right now) into two classes: Those who can afford it, and those who know Kier and Mike, love the software, and want to support the project but are forced to watch from the sidelines because the license is too expensive.
Yeah, the software is great and all, but I can't see how some of you are seriously suggesting paying $250 or more for a version 1 alpha product.
My advice to the team would be to make it cheap to start with (especially with the early adopter sale), so that almost everyone can afford to get a license and everyone is included. Start with a really strong community where (almost) everyone has a license, and then let the software grow in value as the community builds and you add features. If you come out with it priced at $250 or more, I think you could potentially kill a lot of the buzz by excluding those that can't afford it.
Just my opinion.
