MSI will not be joining the USB 3.0 / SATA 6.0Gbps implementation trend that has been recently started by Asus and Gigabyte, as according to MSI it doesn't make sense, at least not yet.
We must agree with MSI on this one as there is not a single device on the market that actually supports either of these new standards, and although the implementation might give you a future-proof motherboard, we must wonder how big is the extra cost that you'll have to pay for such a motherboard.
As far as the USB 3.0 goes, Intel's has postponed the implementation of it in its chipset to 2011. The SATA III or SATA 6.0Gbps is a similar story as well, as traditional HDD's are doing fine with SATA II, and SSD's, the ones that are only one that will benefit from SATA III aren't coming until Q1 next year.
The HDD companies are scrambling to support the SATA 6.0Gbps, and Seagate should have its Barracuda XT 2TB up and ready pretty soon, but according to some of the first reports, it will have a premium price of US $299, and performance gain will not be drastic. On the same note, SSDs are yet to become affordable as currently these are limited to enthusiasts with deep pockets.
Don't get us wrong, as MSI is working on mainboard that are equipped with SATA 6.0Gbps and USB 3.0, but they won't be announced until it makes sense to do it, as for now it certainly doesn't. After all you can always get a SAS / SATA controller if you really want to go for the new SATA 6Gbps drives.
