As a potential byuer I am happy to know that but at the same time a bit worried... If we buy Sygic for Maemo now and they will launch Aura a few months later, will we have the option to upgrade it, even paying an extra fee? Or will we need to buy it again at full price?

I guess even iPhone owners who bought Sygic are wondering this right now. It would be good if someone from Sygic can confirm their upgrade policies.
