It's highly unlikely there'll be TL trains to King's Lynn, due to its
ongoing reworking as a high-ish frequency inner suburban service. 5
car Intercity Express trains (equivalent to 6 cars in length) have
been suggested for King's Lynn/Cambridge, running to King's Cross.

That's a major change not mentioned in Cambridge so far.

I don't think it has been explicitly mentioned anywhere Colin. But a number
of conclusions can be drawn from stuff like the IEP and its route specs, and
the more up to date South London RUS removes a fair number of the Southern
destinations such as Littlehampton and Guildford, shown on older Thameslink
diagrams. Unfortunately there is no combined 'Thameslink RUS' to fill in the
missing northern branches. Can't see where it might appear either - East
Midlands perhaps?

My personal suspicion is that they've decided that Kings Lynn is just a bit
too far for the high capacity inner suburban style train they really need.
Having long and short distance train variants through the centre section
doesn't really wash AFAICS, no matter what is suggested in the Thameslink
spec.
