They have merged two snippets into one I expect.

Indeed complete nonsense! *H&C / Met / District / Circle line stock
will be replaced with S stock, starting from later this year -
http://en.wikipedia.org/wiki/London_Underground_S_Stock

It's just confusion between the new class 378s (as used by London
Overground on the NLL, WLL and ELL) and the upcoming LU S-stock -
there are a fair number of similarities, though ultimately they're
rather different trains.

It surprises me that TfL could not come up with a common design for
Overground and sub-surface stock.

Why? The infrastructure on which the two types of stock will run is
quite different. The LO class 378s need 25kV AC supply as well as DC
(for the units on the North London Line) and run on routes which can
take 20m coaches. The S stock will be DC only, and parts of the route
would struggle to take the longer 20m vehicles seen on the class 378s
(the S stock is 16.7m per coach).
