Yeah, I've done only the 4 cylinder engines so far, the 1.6 and the 2.0. Nice setup actually. Even with DOHC, they manage to make it a pretty easy job. The exhaust cam is driven by the crank via timing belt and sprocket. Then, at the other end of the exhaust cam there is a small sprocket that drives the intake cam. This is also the location for the CVVT system (variable intake timing). Timing them is easy, the cam never slips if you're at TDC, and the tensioner setup isn't bad. They're still using V-belts, that's the only pain - so you've got 3 different belts to take off before you can get down to the cover. They recommend service at 60k, but the timing belt always looks great.
