Asked my Husky dealer the same thing today
He called his Husky rep and asked while I was there. The answer we got was realistically late April to early May for most dealers.
We also asked about whether the 562 XPG would be available in the Northeast. Answer, he thought so, but couldn't be 100 percent certain. As Stihl sells the MS362 around here with the Arctic Package I would think they would want to offer a competitive product in this area.
And that's straight from the rumor mill.
