I read this, and some of the mobo is on sale in my local computer shop. So I thought other manufacturers already released some AM3+ mobos as well.http://www.bit-tech.net/news/hardware/2011/04/07/gigabyte-announces-am3-black-socket-motherb/1
it actually make sense to release the mobo first and then the processor.
people who needs a computer NOW could buy a Phenom II with an AM3+ mobo,
so the upgrade path is open for the next 1-2 years.
