I have a hunch First Class will be abolished before the 700s enter service, in which case some longer-distance commuters can bag the better specified areas with tables and sockets.
Given that places like Haywards Heath have some of the highest first class revenues in the country I doubt it personally, thats why first class was retrofitted to the 319/1s
If I can summon the energy to stay up late enough I'll head out and see if I can catch it this time
