no, even the ww foods sold in shops will have the old pts on untill new year, tesco & other stores may follow as well, you can still work out the new pro pts from the info on the pack x
as far as my leader told me, it will be but gradually. Seems that the new plan will be finishing its "pilot launch" in January. We're just getting used to it now. You will therefore need to calculate the pp value of *all* ww food, unless you see "PROPOINTS" written on it!
