Thameslink to London Bridge is closing from 20th December until 2018. Beware!
FWIW, if you're taking the Piccadilly or Victoria lines from King's Cross, it's far easier to use the southern ticket hall (near the old front of the station) - particularly the lifts which take you right down to the platforms.
