I don't think so, coz no optical drive can reach the speed of SATA or even ATA133 in the near future. It's just too much cost and trouble for the manufacturers to migrate their optical drives to serial considering the fact that higher data transfer rate means faster speed (eg. > 16X for DVD drives) that need to be achieved, which also means some technical difficulties like noise and vibration that the manufacturers have to overcome first.
SATA has benefits beyond just it's speed though. Namely: The much smaller cables can clear up a ton of space inside the case. I dont claim to know a whole ton about SATA, but I would think it'd be beneficial to switch over at some point, even if the optical drives arent utilizing the full speed capabilities of the technology.
