The Japanese company Art Storm has announced a December release of a set of high-end die-cast toys of the original Gatchaman vehicles. The vehicles will be 10-15cm in length.
They'll be released in two sets of three vehicles each:
Set A: G-1, G-2, and Red Impulse plane. (Link to image)
Set B: G-3 (with Jun riding) G-4, and Godphoenix. (Link to image)
The only bad news is the price. If you thought the Cho Shin Gokin Godphoenix was expensive, hold on to your hat. The vehicles only come in sets, and each set will cost 24,800 yen.
When these items come available at the end of this year, and if you have about $510 burning a hole in your pocket, I suggest checking Hobbylink Japan to order.
Thanks to Tatsunokofan for the info and photos!
