This is an interesting question. I've always assumed there would be some form of access in a manner similar to that at Southwark/Waterloo East, partially prompted by the proposed re-branding of the station to Blackfriars and Bankside. However your post prompted me to look at it a bit closer and I found this bit on the TfL website about Blackfriars tube, listing the benefits upon completion, it makes no reference to access directly from the Southbank, nor do the photographs of the Southern station have a Tube sign branding...
Anyone else know anything concrete?
