So seeing that variable valve lift technology is soon to arrive en masse, eliminating the need for the throttle body to do anything, how do you guys think this could affect intake modification?

Some intake designs are already decently optimized. The EJ251 and EJ253 N/A Impreza and Legacy engines sees almost no performance or economical gains with a upgraded/aftermarket intake systems. Only the CAI systems provided gains because of the location of the filter.
and those are ones without subarus VVL and drivebythrottle.
If we throw in the drivebythrottle mix, it greatly effects how mods are registered.
