See, I really want to get back to buying just one of each to fill out the squad. The problem is that I fear they will release multiple upgrade parts for each fighter. I tend to buy one dedicated valk per fast pack/armor/whatever pack that gets released. I don't really care to mess around with them that often once I get a set of parts on and have it displayed in the mode I want. Now as far as the 31-A, I see myself getting a minimum of 3 of those. With my line of thinking and Bandai sponsoring the show, there is a chance that I would need 18 VF-31's plus 3x 31-A's.
