4tph Metro via Denmark Hill to Victoria sounds good. Also the Hayes line will seem a lot more attractive offering services to Victoria and Charing Cross over Cannon St.
The loss of Hastings services at Orpington will be frustrating. If I wish to travel to Hastings from West Dulwich, this will require a three train change at Orpington and Tonbridge which isn't ideal. At this rate, I'll probably end up travelling via Zone 1 to London Bridge and board there for the convenience, although it'll be at a premium.
There is still of course the option of travelling via East Croydon on Southern, but is too long.
