No snub at all.
Dez didn't come on until late in the season. Before then he had his fair share of negatively memorable plays (e.g. Bad routes vs. Chicago leading to Romo INTs; missing a game winning TD by a fingertip because he falls in the endzone with poor form, etc).
By the time Dez turned the corner much of the voting was in.
It's up to Dez now to build on his performance over the last 5 games, clean up any remnants of miscues, and carry that performance over a 16 game season (and through the playoffs).
If he does that he'll be a lock for next year!s pro bowl. Dez holds the keys; it's all up to him now to have a strong offseason to achieve that.

Trent Dilfer: "Tony [Romo] has greatness in him. I think when you talk to other people that really play the quarterback position, there's a few guys that really have incredible greatness in them, and Tony is one of them. I think the issue here is he needs more help from his teammates. I think they are not nearly as talented as people say they are, from 1 to 53. I'm talking about the total roster.”
