In keeping with the post a few above, I don't think they can release the mintages until after the end of the calendar year. Whilst they might know in advance for the commemorative crap marketed to the masses, a regular currency piece's mintage will depend on the demand from the banks for coin. If they don't order it, the Mint doesn't produce it.Yes, i still find it odd though. We've known these mintage figures for a while so why wait until now? Surely the banks don't ask the Mint for Kew Gardens 50p's (for example) do they? I would have thought they would just ask for 50p's, then the Mint can decide whether to produce/send regular coins or commemorative ones?
