I, like many fans, didn't expect Britney's first performance to actually be Vegas, but I'm not distressed about it and it isn't a source of disappointment for me because I see that the show is shaping up to be amazing. And what can go wrong with an amazing show? Nothing to complain about if Britney delivers.
Musically, I'm very satisfied. I love the album.
The music videos are shaping up to be great. Work Bitch video was fantastic and one of her best videos in years and the Perfume video is directed by Joseph Kahn and Joseph + Britney for a music video can never go wrong.
The photo shoots have been great. The album booklet is better than all of the others sans
Britney. In general, she's looked really great this era.
Commercially...

That's probably the biggest disappointment. A lack of a hit single can really burden fans and the album era as a whole. But that can be fixed if It Should Be Easy is the next single so I'm not too concerned.
