The upgrades to the older rotax motors should keep them competitive…. If not you’ll probably see a lot of $300 motors on the market!
I’ll be upgrading to EVO parts for my son’s Junior, but I’m not optimistic that the old parts will have any value at all, except for the hobby market. The outdated parts are just that, old. Come mid 2015 I would expect used, non-updated rotax motors to be much cheaper. IMO
