To be fair, it's not like you didn't have warning. I think Empeg is being very reasonable with its discount and I don't see why there should be too many more consessions on their part.
...I was aiming to leave my upgrade for a month or so, to see how the software and stuff settles out (especially since the tuner isn't available immediately and the VR software is delayed too).The software is very good. there has been far worse PC software to come out as version 1 or higher.
Windows? 
To defer for those reasons is pretty lame. My Empeg didn't have half the functions it does now but i haven't had to outlay anything more for the upgrades
Besides, what are you
really waiting for?
-Money? yeah, things can be tough.
-the next best thing? you'll be waiting a while.
