Tobu's only previous limited release was their 8000 srs 3-car in 2007.
The 2018 S-51 C11-207 (also Tobu railway) had two headlights, the new version C11-325 just has a single light.
Apart from that the only difference appears to be the number and the drumhead stickers. The caboose is the same Yo8000 type, and as Mr No says, the coach is the same SuHaFu14-1 conductor car with blacked-out windows and no rear coupling. Some more intermediate blue coaches would be really welcome.
