Now if they're planning to make in-game advertising instead, they should really not go the way they went with WipEout Pure and the Delta Packs. They were plastered with hige ads all over the place. Even the ships.

Discreet advertising is the way to go, if you ask me. If you can find ads just one a single time per track (and not on every track!) it's like "oh look, there was an insertNameHere-ad!" At least that's the way it was in 2097 and Fusion. It had a "That's cool"-effect rather than being in-your-face.
