The slueths over at VR-Zone have come across some photos of the upcoming Gigabyte Z68 motherboard option, the Z68MX-UD2H-B3.  The VRM setup is a 6+1 design which is pretty basic though the inclusion of three full-size PCI Express slots should allow for at least dual-card configurations of SLI and CrossFire and possibly even three cards.  

VR-Zone has more info on the configuration options as well:

Moving on we have a header for two front USB 3.0 ports via an Etron host controller, no less than five headers for 10 USB 2.0 ports, seven SATA ports of which three are SATA 3Gbps and four are SATA 6Gbps and for some reason a serial port header.

Around the back we have four USB 2.0 ports, another two USB 3.0 ports using another Etron controller, an eSATA port, a Gigabit Ethernet port, a PS/2 port, 7.1-channel audio with optical S/PDIF out and a set of four display ports consisting of a D-Sub, DVI, HDMI and DisplayPort.

For those of you that love the mATX form factor seeing reasonable designs like this one are good indicators that the Z68 market is going to have just many options as the P67 one did.
