My prediction is that few people will be satisfied with it. This errata/points adjustment has been built up so much that it is meaning everything to many people. Some are hoping their faction will suddenly get massive points cuts, others are hoping their hated faction will be nerfed into the ground. I've seen plenty of speculation on massive erratas to older units to make them on par with brand new units. Chances are, the changes will be relatively minor. Couple points here, couple points there. Maybe the big characters or tanks will get a 10pt drop or something, and maybe a few units per faction will get an errata, but that's probably about it.
My hope is that people reign in their expectations, and allow themselves to be pleasantly surprised when they do get a nice change.
