There's always going to be someone disatisfied with the releases that they do. So it may make sense to you for them to do one thing and not to someone else. If they released a variation of Roy's valk, it may make you happy but you know some other "completist" is gonna get upset cuz they have to get one with the small differetiations. "WTF? I got to get this one now just because it has a little gray pilot?"
Also, from what I learned here on MW and looking it up after. It seems that the stripes on the arms has nothingt to do with DYRL vs. TV versions. Only the VF-1J arms has the panel lines that go horizontal because it's manufactured by a different licensee.
My point simply is that the TV FPs cant be released "stratigecally" because you cant really sell it with any other valk. The 1S gets the strike, the M&Ms get their custom FPs, that would just about leave the CF as the only viable valk to be able to recieve the TV FPs. And as far as the 1/48s were concerned we were all pretty suprised to see that valk get made at the time.
