Jake,
Yupper! Only time will tell w/ the IMS-less. However, simplicity in engineering is always the best ingredient for a successful product.
Southernstar is correct with his statement; there's no argument about that. If I understand your implication/statement correctly, then no body is questioning the decision that porsche made to use the IMS b/t the crank and cams but many people are questioning the use of the roller bearing on the IMS. When a highly sought after company changes the design of their engine drastically, deleting IMS, their confidence in previous engine design is questionable. I'm not saying it's a problem, but it's extremely questionable.
Prior to 1996 when the Boxster came out, what type of bearings did they use for the IMS?

A Porsche overhead cam engine has utilized an "IMS (aka layshaft) since the mid 1950s, beginning with the 547/1 and that was done for a reason.
