Don't know if you are still looking for this, but it is coming avialable in Canada this month. Some online retailers already have it on hand / on order. Check CDW, DirectDial.com, etc.
I got one this week and have started playing with it, but can't answer on the dual WAN as I don't require it. I don't recall seing anywhere that said it couldn't do it, I assumed it could. They did release a firmware update the last week of December, so that may have done the trick.
