I wouldn't mind that...but I doubt it. When BBTS upped the price of Toynami's Cyclone pre-order (from $79.99 to $199.99), the email notification stated that Toynami had given them the MSRP and if retailers didn't stick to it, then orders wouldn't be filled.
So, my guess is this: If the Beta's listed price is inaccurate, BBTS would've been told by now.
