Whay aren't all of you just DEMANDING your deposits back if you actually want out?
They are in breach of contract and there are consumer protection laws that are in place just for this very example (i.e. missed promises of deadlines, changed product, lack of clearly and publicly posted pre-order policy > note the policy does not mean jackshit once they have breached for changing the expected product and missed delivery).
There is a reason you have not seen PPS of any of the distributors comment on the above fact and that is because they know it is true and are scared of what happens.
Keep in mind that many distributors HAVE given back full refunds so this is obviously on an individual basis.
I suggest if you want out then you had better do it sooner rather than later.
If you also want to play along with their stupid BS games about "you can't get out untill you sell your spot" then you should ask them how many people are in front of you to get out?
