Are talking about 10 times increase (10 x 1 = 10) or ten fold (10 folded = 1024)?

"10 fold" is the same as "10 times" you dummy.

Compability? Does Express Card 2.0 compatible with 1.0 or vice versa like USB 2 and USB 1?

One has to wonder about the knowledge level of an author who cannot distinguish PCI-x(sic) (PCI-X, PCI eXtended: a computer bus and expansion card standard developed jointly by IBM, HP, and Compaq in 1998 that enhanced the PCI Local Bus for higher bandwidth demands) and PCI-E (PCI Express, officially abbreviated as PCIe: a computer expansion card standard designed to replace the older PCI, PCI-X, and AGP standards. Introduced by Intel in 2004). It is a common novice mistake.

"The new 2.0 standard will utilize PCI-express 2.0 as well as USB 3.0."

How many lanes of PCIe 2.0 is alloted? 4-lanes?

I'm trying to understand how buying an ExpressCard 2.0 device with an eSata port would help someone with an ExpressCard 1.0 port (i.e. a 6-month-old laptop)? What does this have to do with the rest of the article?

Wikipedia says it will be reverse-compatible with ExpressCard 1.0, which would make sense as both PCIe 2.0 and USB 3.0 are reverse compatible.

10x performance over ExpressCard 1.0 would mean 5 PCIe lanes, an uneven number. I think the 10x performance is purely from the aspect of USB 3.0 (rumored to be 5Gbps vs 480Mbps of USB 2.0). In all likelyhood, any devices using PCIe would only be twice as fast, and the on-paper 10x benefits of USB 3.0 have yet to be demonstrated.
