The biostar board was the old nforce3 150. The only board coming out I can find is a soltek SL-B9A-FGR. It's a small matx board with 1 agp and 1 pci slot. It's on soltek's website, but no reviews yet that I could find. It may not even be available in the usa, as soltek doesn't sell too many boards here. Your best bet looks like the gigabyte sis board. If you're really interested in one of the 3 brands you mentioned, I would call them direct, and ask if they have any matx boards coming out. I couldn't find any info on their websites.
