This is a bit of a strange case. Kono confirmed the diecast models are indeed officially licensed products, but even he didn't know they were already released, and that was in December 2019. Based on what I heard from the Taiwanese ex-Infinity players, those models were released in late November.
Damn, now that I'm looking this up, they were indeed released last year... damn. Now that I know they're out there, I'm going to try to snag one. Thanks for the post, I honestly thought they hadn't come out.
What's stranger was that Project Aces never announced it, and the only "official" site that showcased the models are from a Facebook page, so you and me found it very suspicious back then. Even after reports of models being released, Hobby Search and a few other sites' status was still on "reservation closed". I had no idea when those sites actually had them in stock.
@Lectro 001 Yes, that is an officially-licensed model.
@GeneralErichVonBleinspeiler That's a different model, that's a plastic one. We were talking about the metal diecast models of the F-15 Pixy and F-14 Razgriz.
