Well I'm more keen on what it was they added and what changes they've made if any with the feedback that most folks had during the closed beta. Characters carrying over or not doesnt really matter much to me if I'm honest.
I've played a lot of MMORPG Alphas, closed and open Betas and almost none of them allowed for your alpha/beta progress to be carried over. Ever. Allowing that would only make the keyboard/forum warriors to cry and rage over the forums. I don't mind that they'll wipe everyone's progress before going live. Why should anyone have lvl20-30 characters 2 minutes after logging in on day one? Alphas and betas are there for testing, not demoing or jumping into the game early to get an advantage over the others.
As for the added content, they've basically tweaked the Dark Zone a bit and increased the NPC mob density, removed some glitches, turned on the anti-cheat stuff for PC and other minor stuff.
