I can confirm that at the moment we are not expecting significant reductions to London Bridge. The December 2013 (I read that as 2012) timetable change was planned to cater for the known platform changes at London Bridge.

In May 2013 we expect one train to be diverted to Victoria, this will be the 0725 from Tonbridge to London Bridge (which does not stop at Forest Hill). Beyond that certainly through until December 2014 the structure of the timetable should stay the same though there may be some minor retiming needs as the works progress.

From December 2013 we are expecting to lengthen more trains to and from London Bridge when the new Class 377/6's arrive.
