We're going to get 3D ads. This is not a maybe; the ability is there, so it will happen. Anything else is wishful thinking. And they won't be rotating cube demos - no, the designers will instance an entire 3D engine, and they'll start dumping in expensive shaders and high-poly models that "work for them" on a high-end desktop. And then web sites load three or four of these ads. No optimization or acceleration is going to tame such monstrosities. Your netbook might hang just trying to load the page, forcing you to use an ad blocker whether or not you want one. The long-term solution is for ad networks to minimize client-side tricks and stick to safer performance envelopes(images or video).
