The reason I sold off Universe Nemesis Prime is that he didn't go with anything else I had, the same is true now I guess. I'm trying to be more focussed on Masterpiece and black repaints in these days of (baby induced) belt tightening, he doesn't go with either.
I guess Takara will eventually do a MP Skywarp 2.0, but they seem to be in no rush (maybe MP-6 Skywarp and MP-7 Thundercracker were slow sellers). I'm not so sure about Hasbro, as they tend to be picky about which Masterpieces to release. I'm considering hunting down a MP-6 again.
I liked googly-eyes too, but I tend to get bored of my avatars fairly quickly. I've always like your Black Big Convoy avatar, he is a grail of mine, although the chances of me getting him have receded into the distance.
