Closed Will preorders still be available when beta is out?

I'm unsure, and felt I really needed to know.

Will the special preorder options still be here when beta is available, up until release? Or will they get taken away?
I ask this because I'm trying to make a decision between buying one of the higher preorders or waiting a while.

 

The current price of the pixel tier pre-order is lower than the planned full price of the game. There is a possibility that this will no longer be available when beta starts. It's also possible that the devs will chage their pre-order system once beta starts. My guess is that the multiple tiers will probably last at least part way through beta, but there's a definite possibility that they will be discontinued once beta begins.
