I am also a bit worried about some of the wording and what will happen if they don't reach their goal... I've "bought" one copy of the pro version (at about £25) through paypal hoping that if there is a problem then paypal will get me a refund.

On the bright side - the green bar on the shop page appears to be moving so they are at least on their way to this mysterious goal.

Caveat emptor :)
