As said in PM I've sent you few weeks ago (as reeply to your question about preordering - I have never got answer, maybe you've missed it?), currently planned price is:

Flat backcover: 50$
Fat backcover: 70$
Body replacement (inc. flat or fat backcover): 200$

Prices can change either way - as always, people who already pre-ordered are immune to price increases, but *do* get refund, if final price will drop.
