Sorry if this seems a little off topic, but I just caught this news the other day and did backflips. Some members of the team behind the Pro Pinball series have a new development studio named Silverball Studios and they are starting up a Kickstarter campaign to not only develop a new Pro Pinball table, but completely remaster the originals! At the moment, if they meet their funding goals, they plan to release them on Windows, OS X, and iOS. No Linux version is planned as of yet so Crossover will still be relevant for Linux users. Hopefully though, by remastering the game with a more modern engine, the game will be less problematic in playing under Crossover. Definitely keep an eye on this if you are a fan.
