I'd hazard a guess that he doesn't have them edited and done up to his standards yet but it will be worth the wait.
I think he's just teasing us, making us wait with great anticipation. The suspense is killin' me. He was still posting single shots from last year just a week or so ago. And you're correct, his stuff is extra special.
He put his first pic on Facebook yesterday. He does quite a bit of photo editing and special effects. I'm sure we will start to see them soon.
