They've been busy for several years digging new tunnels to the 3 sets
of tube platforms and building a brand new ticket hall. It all opens
December this year,

The newsletters you link to, below, all say 2010.

which means they're only just now getting on to the cosmetic finishing
off, which means the refurbishment of the platforms.

Have a look at some of the PDFs here for an explanation:
