See above. It may happen, it has been requested but no demo during a preorder period is not unique to this product nor unique to IK. I'll do what I can but there's always the option to wait and not save the $ (which is also neither unique to this collection nor IK).
Edit - I appreciate your business suggestion, and as stated earlier in the thread it has been relayed (I've been doing so since the first day we announced it). If it doesn't happen, though, this will be no different than other preorders and nobody is putting a gun to anybody's head to preorder and it will be available afterward... just at a higher price.
