We are in a great deal of need of an AGP 16x - it would be greatly useful for beating back PCI-E.
But in the end; its down to what the Motherboard Makers want to make. If they don't bother with AGP anymore and keep it at 8x, PCI-E will be taken. If they push for AGP 16x or 32x and so on, we'll use AGP.
