There is an incredible listing of point drops + weapon upgrades mentioned in this video. The big thing is that his information matches up on the release date with a very solid source here on Faeit 212.. which is pre-orders June 2nd and a release date of the following weekend!!!

Valiant - Thundercoil harpoon - heavy 1, s16 -6ap, 2d6 dmg. Reroll hits vs vehicles and monsters +d3 mortal wounds if you cause any damage.
Valiant - Conflagration Cannon - 18" range, heavy 3, s6, -1ap, 2 dmg, autohits. But also says heavy 3, d6 dmg, so i think something has got mixed up here.
