They need not go the full sabretooth, just a mid range type affair would be an upgrade to what us ITX AMD APU users had the option to chose from. Asus didn't produce any ITX boards for AMDs APUs whatsoever. Which is really lame since they produced a nice ITX Z77 at the time. Gigabyte were very late to the party, asrock had power/heat issues and MSI and Zotac boards were very entry level to say the least.
I can vouch first hand for the mosfet A75 heat issues, yes. Luckily I noticed the problem before it combusted and mitigated it with a heatsink and undervolting and underclocking. I believe I have also read about the A85 having similar but less severe issues too. I have heard good things about their bigger boards but this has put me off Asrock for life.
