"Today I can announce that the next new Typhoon squadron will be Number 9 Squadron, and will start to form at RAF Lossiemouth later this year."
That quote says nothing about when the Tornado unit will cease to exist. It's perfectly normal for a shadow unit to build up ahead of numberplate transfer. NB the word 'start'.
Ah, the media ;-) As there are no quotation marks around the information in question in that article, I think the word of those currently planning disbandment events for next March probably wins!
