We already started BitSafe integration, and plan to do Trezor as well. Slush has tried contacting me a few times but I've been super busy (for obvious reasons), and figured I'd back to him when I have the resources to execute it. I also thought I had more time, but it looks like Trezor release is closer than I realized.
Support will be there. It's going to be higher priority than the new wallets, actually (because it's very easy to integrate with Armory). We have a new guy coming in at the end of the month who has the perfect skillset for doing this integration.
