Honestly, right now the things I am looking forward to the most are:
The "High Tech Assassin Suit" - which is basically an LA version of the Medic Power Armour from FO3, except it dispenses Stimpacks instead of Med-X and has a female voice computer which tells you how your supplies are.
The HMG that they're adding, aptly dubbed the K9000 according to the wiki. Not saying thats what it will be called, I just find the Doctor Who references in FNV amazing. :rofl:
The Sonic Baton - Simply because an Energy Axe is AWESOME.
and the Sonic Emitter pistol, just because I'm curious about the upgrades.
Also curious about the new craftable weapons they're adding. :fallout:
