I'm waiting to also start a new character.
Honestly, I will be surprised if Lag is even addressed in this patch. I got the feeling this next patch was mainly to fix the resistance issues and the backwards flying dragons that they created with the last patch.
I thought they said this week but they said it would come out for the PC first. It will have to go through Sony's certification before we see it.
Yeah, I'd be surprised if it does anything more than fix those two issues. Or claim to fix them, anyway.
Chances of it coming out tomorrow are slim to none, since the PC patch isn't out yet - which means Bethesda are knowingly unleashing a totally defunct product on Japan's launch day. I feel sorry for the folks that go for a day-one purchase over there.
