My trial of Aperture 3 has just come to an end and I've decided to purchase it. However, having been caught out before with buying from Apple then hey presto the next week a newer version appears, I'm thinking of holding off for the next version. Looking at the Aperture history version 2 was released in Feb '08, v3 in Feb '10 so I'm guessing v4 is imminent!?! Have i got this right? Anyone got any insider info?
