Nope you didn’t read this wrong… If you already own any version of Reason AND any version of Record. Then from 30th September to 31st August 2011 you can pay what you want for the upgrade to Reason 6 (although there’s a minimum of $1/1EURO).
There’s no catch at all, and the only thing is it’s only a downloadable license (i.e. you get no boxed product), but it’s a full version of the license with no catches.
