I am in the same boat as to whether or not to buy now or wait. It's trickier for me as I live in Turkey and would have to pop over to the UK to pick it up. I am going anyway this winter but was planning on going in the next couple of weeks. However with nothing booked can put it off a few weeks.
Whilst I am sure that the current version is more than sufficient for my needs, if as is surmised above the new version will have a more user friendly interface and therefore a shorter learning curve it would well be worth the disruption to my plans.
Cheers Steve
