Revell AG - The Porsche 934 race cars are still coming. Seems like back to classic cars, or perhaps expanding the DTM series forward. There was talk that if the 570S sold well enough it could spawn further McLarens, but considering it was just released it might be to soon to expect anything of that nature in 2017. But this is the easiest one as they'll announce their 2017 slate in 3 days.
Tamiya - Honda/Acura NSX Type-R anyone?
Aoshima -
Fact - Diablo GTR (race car based on the GT), D1 Grand Prix HKS Toyota 86
Conjecture - '17 Nissan GT-R, '15 Crown Athlete (minor front end revision as was done to the Crown Royal Saloon), another version of the Pagani - there are parts on the runners that aren't used in the kit as issued. A Huayra BC or Roadster?
Fujimi - AMG GT GT3 - there were 3D renders done for this already. Who knows when in 2017 it would come out since the '15 Toyota Alphard/Vellfire van kits seems to be stuck in a delay time warp.
Hasegawa - Another variant of the N360 (still parts on those runners that haven't been used on either kit), and a 2nd variant of the new Jimny.
Belkits - '15 & '16 VW Polo, and Opel Manta 400 x2. Be interesting if there's further product development at Nuremberg Toy Faire, since the Polos just need approval from VW and the Opel is finally going into the first stage of tooling.
Beemax - Toyota Levin AE92 Gr. A, Brabham BT52, Quattro S1, Lancia Super Delta, Volvo 240 Gr. A. Also the next variant of the Civic, and two more variants of the BMW M3.
