"Sherlock: Series 3" Not On TV Until Late 2013/Early 2014!

It's been reported and confirmed that filming for the third series of hit BBC show "Sherlock" has been moved to March next year and may not air on TV until late 2013 or early 2014 at the most.
Filming was originally confirmed to start in early January for a Summer 2013 air, but not that seems as though that ain't going to happen, which is very annoying because we may have to wait for another year/year and a half if so.
