2004-06-01 MXM, Axiom nVidia has created MXM (Mobile PCI Express Module) while ATI created the Axiom (Advanced eXpress IO Module). Both are based on PCI Express, but with a form factor suitable for notebook graphics cards. In MXM three versions are planned:
MXM I is geared toward thin'n'light laptops, MXM II to mainstream machines and MXM III is intended for desktop replacements.
ATI only has two form factors for thin'n'light and performance machines.

2004-06-21 PCI Express PC interconnect formerly known as 3GIO. Evolved from PCI and the physical interface of InfiniBand to a serial high bandwidth interface which will be used both as a PCI / AGP replacement and for chip to chip communications. Runs at 2.5 GHz and 0.8 V today, but will move to 5 GHz in PCI Express 2 in 2007-2008, and later to 10 GHz. Provides independent channels for each direction. Multiple bus widths are available:

From PCISIG:
"PCI Express currently runs at 2.5Gtps, or 250MBps per lane in each direction, providing a total bandwidth of 16GBps in a 32-lane configuration. Future frequency increases will scale up total bandwidth to the limits of copper and significantly beyond that via other media without impacting any layers above the Physical Layer in the protocol stack."

Will also spawn a successor to the PCMCIA (PC-Card, CardBus) slot, 3GIO-M, Newcard or ExpressCard, which includes both PCI Express and USB 2.0 interfaces.
