Any infos yet on Absolute 4?

Are there any infos yet what will be new in Absolute 4?
Reason for my question: I am on Absolute 2. If I update now to Absolute 3 (for 100 €) the subsequent, upcoming January upgrade to Absolute 4 will be free of charge.

However: if it comes with nothing more than the upgrade to GA5 (and addition “cosmetic” changes) I’d rather pick the current 60% from Halion 5 to 6 (and skip Absolute 3 (or 4)
