B&H Photo has the following CF cards on sale:
Lexar 32GB CompactFlash Memory Card Professional 1000x UDMA
I put one in my 5D MkII and it sped up the fps and increased the time required to fill the buffer substantially. Not all cameras need this fast a card, but the 1D X and the 5D3 really benefit substantially from a fast card.
They're back ordered, but the price is almost $100 less than last week.
