My understanding, correct me if I am wrong Ski/Hawker, is that GB will be added to HB2 as a paid plug in. Anyone that has GB access at the time will then be able to use the HB2 plug in. This plug in will enable gathering and flying in HB2 for everyone that has the appropriate skills on their character. Basically it will eliminate a good amount of the support required for GB and make it a lot better by using the new nav system. It will also enhance your HB2 by creating better gathering, as the current HB1 has issues getting to many nodes and of course can not fly.
