When are the TV games announced?
I wouldn’t have thought before all the replays are done with which would be a week on Wednesday. There was a large number of draws in R1, something like 15 replays to take place including the likes of Bromley, Wrexham & Sunderland, all of whom would have a fair chance of being on the TV. I would still proceed if trying to do some planning on the basis that we will probably play at 1245 on the Sunday.
I agree with all of that, and add for rail passengers that trains are not going down the faster route from London via Guildford (this applies on Saturday, too). There are replacement buses, but the better bet is to take a train which goes a longer way round via Eastleigh. The route to the north and midlands via Reading is still open. Fratton station is very handy for the ground.
If anyone fancies making a longer weekend of it and coming back on Monday, the RMT have declared a strike on South Western Railway that day, along with nearly all of December!
