Sandisk Extreme/IV 16GB cards

Guys, Quick questions, I've been looking at the newer Extreme IV 16GB cards that are UDMA 45, however seen some "Extreme" that are 60GB, but its just called Extreme without a number, are these better? I'm aware that the Pro editions are almost double the price at 90m/s transfer rates. Much advice appreciated before I purchase. Just bought at 7D so upgrading a few 4GB cards for pic taking, and 16/32GB cards for video :)

Extreme III and IV as well as the Ultra II are no longer manufactured. The new extreme line up is just called Extreme and Extreme Pro with the data transfer rate on the cards. The Extremes with 60MB printed on them are part of the new line up.

Might have to stick with the IV's then, as wanting 2 and 4GB cards for the pictures side. Thanks for the info fella :)
