For those wondering what MBNA card to switch to - MBNA says all eBay cards will become worldpoints - not worth anything IMO.
I will try to merge my eBay card with my Merrill card. For those that do not know, 50K spent will get you 50K Merrill points AND 4 Ritz nights. The Merrill points can be used for flights directly - 25K points for up to a $500 flight - domestic or international. OR you can convert your points to BA miles 1:1 with no converstion fee. The Merrill card has no annual fee and seems to be the best MBNA offering for the time being.
