For me
1) I don't like the nano-trites concept. If I die I want to be dead and I want to go to the last checkpoint instead of getting insta-revived on the spot. I hope it plays well into the gameplay and I actually feel that the nano-trites were necessary.
2) I know there are more awesome weapons to come but right now I don't like anything but the wingstick. Rest just seem generic. Plus they should disable auto tracking on the wingstick (at least on higher difficulty and MP) so that using it actually requires skill and people can actually show it off.
