OK, if we are going to be serious about this.......
not so much new technology but how about an increase in the size of the BIOS chip?
At the moment Gigabyte boards mainly come with 8Mb + 8Mb back-up, if the size of these BIOS chips were increased then surely they would be able to improve the programming and features for Overclocking, CPU, GPU, and other hardware compatibility. One of the main reasons that motherboards can't keep up with advances in technology in other areas, is that the coders do not have enough space for instructions for newer CPU's, GPU's etc., to be added in BIOS updates. Increasing the size of BIOS would surely not cost that much to do but would allow for the extra instructions to be added, as and/or when needed.
People will still buy newer technology as it becomes available but, with a feature like this, Gigabyte boards which are already solid and last for a long time would be a little more adaptable and future proof for those who can't afford a big upgrade.
