They could do motion blur if they wanted to but the small graphical enhancement for the time and effort to get it going is just not worth it to any game developer. 
GTA3 didn't have a motion blur just a big blur. Probably to help out the low fps the ps2 put out trying to run it and to reduce jaggies.
Also how would motion blur need prediction. That makes no sense.
