Looking good to me. The boys look older, and it's kind of funny how gracefully the oafish Bill has aged compared to the playboy Boomhauer. I also like how they're all using new tech except for Hank, who looks very uncomfortable--very much in the spirit of the show where Hank is annoyed by changes and new ideas. Rumor has it the characters are about 8 years older, which would mean Bobby, Connie and Joseph are adults and the babies (Good Hank and Gracie) potentially viable characters for the first time.
Honestly of all the things we know about it, I'm mostly excited about Mike Judge and Greg Daniels being involved. Daniels helped flesh out the initial concept of the show (and directly came up with ideas like Nancy/John Redcorn, Dale being a conspiracy guy, and Cotton Hill, all majorly beneficial to the world building of KotH), and stuck with it until about season 6, which is also where the show started to dip in quality.
