VS11/VS12 schedule changes

Hi,
I have received an email from Virgin informing me of the changes to the schedule next year (I think the changes are for the worst) n(
But doing a search I see the Wednesday and Thursday flights are now operated by A340-300 (in July and August) in lieu of the dreaded and utterly rubbish A330-300 (I know many of you have commented good and bad on the upper class "improvements").
But my question is, why would Virgin change the plane type 2days a week, and what are the chances that this is a mistake and the flight will be operated by a A330-300?
Thanks
