There are precedents for Toho doing something like this.
Monster Planet of Godzilla was an amusement park ride that debuted in 1994 and featured new in-ride footage of Godzilla, Mothra and Rodan using the recent Heisei suits and props.
In 2006, Toho commissioned Koichi Kawakita to shoot new monster footage for Godzilla-themed pachinko parlor game machines, using a lot of suits from the Heisei and Millennium films.
This may be the first time Toho has completely recreated an entire Godzilla suit for something like this. That new Shodaigoji suit looks awesome and I'm glad that they didn't just trot out the Kiryugoji suit and try to pass it off as a Shodaigoji recreation.
