It's actually really close now, demomen might just beat soldiers to the mark.

New weapons also released. Looks like Demoman's trusty 'nade launcher is not going anywhere, the sticky bomb launcher having two replacements with a new launcher more focussed on laying traps, and the chargin' targe. Soldier gets an awesome new pickaxe that does more damage the more health he is missing, and a rallying flag that gives mini-crits to anyone nearby.
