Digital Home Thoughts: Transcend Ultimate 64GB Class 10 SDXC Memory Card

Looks like the SDXC cards are slowly trickling out into the market. Transcend has just announced its 64GB Class 10 SDXC cards, but there seems to be no mention of pricing and availability. Ah, the joys of product launches. Press Release at the link.

I'm curious though; is anyone currently using 32GB cards in their digital cameras? Multiple 32GB cards? I'm sure that once prices go down we'll be buying 64GB cards like candy, but there are many days when I don't even touch 2GB on my 8GB cards...
