(1) London Bridge won't have space to accommodate [the SLL service] as

in tandem with the construction of the Shard skyscraper, because the
developers have to cough up x amount of money to contribute towards the
redevelopment of LB station. (My understanding is that the space
currently occupied by platforms 14-16 will become part of the Shard
development around the base of the tower.)

Huh. Is there somewhere i can read more about this? Will more platforms be
added to replace them? How?

London Bridge currently has 15 platforms and a through line
3 platforms on Cannon Street lines
3 platforms and a through line for Charing Cross and Thameslink trains
9 terminal platforms for Southern.

Until the 1970s the through line did not exist, but there were 15 terminal
platforms. Some were lost in creating the through line, and, IIRC later in
extending the through platforms for 12 car trains, and others were lost in
providing space for the new signalbox.

The Thameslink proposals are for 9 through platforms and 6 terminal
platforms
3 platforms for Cannon Street trains
2 platforms for Thameslink
4 platforms for Charing Cross trains

Some trains which currently use the terminal platforms will run via
Thameslink. AIUI it's not yet clear how much of the layout will be available
during the construction period.
