Look, taken from Wikipedia:
'Celebrity Big Brother 12 is the upcoming twelfth series of the British reality television series Celebrity Big Brother. It is expected to launch in Summer 2013 sometime after the fourteenth regular series, and will air on Channel 5 and 5*. It will air on Channel 5 as part of a two-year contract with Endemol, which secured the show until 2014.'”
That's speculation. The contract between Endemol and 5 is just for so many years (currently until 2014) and the planning permission at Elstree is for so any weeks a year (22 live events, i.e. the launch, evictions and finals).
(Speculation from me) I think how the available live show dates are distributed between BB, CBB or special BBs is up to Endemol and 5 to decide each year.
