Most still have 1. Some will still have 2, but they are being phased out. I have not yet seen a PATA-less motherboard, but they are definatley on the way, if not already here. That said, 4, 6 and 8 SATA ports are common, and support is good.
If you have legacy devices you need to connect, SATA->PATA devices are made, and fairly cheaply, too.
