If the new 2.0 continues with the intuitive, fluidic programming style that the current one has - and which in my opinion makes it far superior than many current commercial systems - then not only would I happily move to 2.0, but would be more than willing to pay.
Just a thought, but when Edgar Vigdal remade Deluxe Galaga for the PC - Warblade - I was more than happy to pre-buy before the finished project, because I knew it would be worth it. Maybe you could go the same way?
As I say, just a thought / suggestion.
