Ok, what makes the 8T crazy at $680?

Amain prices for various "favored trucks":

Kyosho STR - $659 - wasn't it $770 when they first released it?
Losi 8T - $649
Mugen MBX5T Pro - $589 - still pretty accepted
CRT kit - $569 - old favorite
LSP-R kit - $429 - old favorite

So, how long will it be before the 8T is less than or equal to the price of the Mugen? And, would anyone still buy a Jammin when the Mugen is only $20 more?
