If you look closely at the Battlefield 3 teaser (link below), at around 0:19 and 0:20, you can see a soldier in what appears to be WHOT. If that means we finally get thermal views on our UAV (if it's still a controllable vehicle) and tank/helicopter gunner views, or if we get the option for a thermal scope on our guns, that's great. I guess.

I strongly feel that thermal modes on tank and helicopter gunners are needed, so as to counter the prone. If it is absolutely needed in an infantry class, limit it to only Assault.
Oh, and get rid of the 12x scope, will ya? That's the reason why so many people attempt to snipe in Bad Company 2. If they weren't granted the ability to look so far away, sniping wouldn't be as prevalent.
Anyways, yeah, can't wait. T - 8 days before the Battlefield 3 demonstration at this year's GDC.
