Vodafone Data Charge Revision?

I've heard rumours that Vodafone are about to overhaul their data charge plans? I saw the report about charging €12 per day for 50mb, but that still doesn't hold a candle to T-Mobile's Web'n'Walk.

Will Vodafone be doing a similar plan in the future? £5-£10 per month for "unlimited" use (subject to fair use policy etc etc).
