My guess is this is Alibre.
My guess is that it will be for the modeler only, no 2D stuff, no sheet-metal, no FEA, nothing like that. I think they are following Ironcad's Inovate philosophy.
My guess is they will have at least some exporting (like Step and vrml).
My guess is they know they will reach 100,000 because those that registered are smart enough to register other email addresses 2, 3, 4, or whatever it takes to get there (They only require the email address, so there's no way they can track by real person). So I don't think they plan on "pretending" they got there by lying.
My guess is the product will be sold for <$500, and more likely <$200, after the giveaway. (Which I will also guess they will provide it on CD for something like $15 for S&H.)
I think they knew there would be lots of talk, but I wonder if they thought about how much negative talk there would be. There are going to be a lot of pissed off people once they find out it's legit and they lost out.
I think I will be very happy with my modeler come Aug.
