The projected release date for the 1970's Great western add on? Being a sucker for all BR blue stuff I expect I'll get it regardless but would have really liked it to have been a bit more adventurous than the rumoured 101 and reskinned Western.
I'd imagine Mid March 2021, but only DTG knows what's going on at the moment. The Class 465 should in theory be before the BR Blue pack for Great Western.
