I dunno, I think there might be something here. The fact that the models are being made by Fair Play and not Ludosity might mean this could be a leak from them and not from within Ludosity, in which case they're likely using different tools (i.e. not Unity) and Rep wouldn't even know since he's at Ludosity, not Fair Play. Plus, you gotta admit that those models are suspiciously spot-on, especially considering some of them like Nigel haven't had models since the PS1 era, if at all, and it includes CatDog and April, who were announced not 24 hours before these images started circulating. CatDog admittedly was a freebie since he's been widely known to be on the boxart for a while now, but I don't see how one could pull an April model out of their ass like that; as far as another TMNT character, the conversation was basically between a third turtle and Shredder, and for the mysterious boxart silhouette, people were unironically speculating Movie Dora over her. Unless someone made a crazy read, that means someone had less than 24 hours to cobble together a convincing April model. I'm not saying it's impossible, but combined with the remarkable fidelity of the other models on there, it's something to consider. There's also a couple of other weird inconsistencies like SpongeBob, Ren, and Stimpy having noticeably different models in the second image. Why would a fake leaker make two sets of models?
I dunno. I'm not making any assumptions here, but for now, I think it's worth keeping this leak in the back of our minds. I can see it being real, but I can also see it being an elaborate fake. (And even if the models are real, I don't think that necessarily means Garfield is in; I see him as a DLC pick more than anything, and this certainly wouldn't be the first time a legit leaker mixed fake **** in with real info.)
