Hey, iHave an iPad Syncing Question! Do the iPad and iPhone Play Nice?

As we wait patiently with baited breath (and wallets burning) for the iPad (insert joke here) to grace the world with its presence I was asked this question:
Hey, I have an iPhone that I play games on. If I get an iPad in addition to the iPhone, what happens to my game data? Does it stay in sync?
Interesting question. How will Apple handle the iPad? Will it be a companion to the iPhone and share data or will it be a standalone device? Surely Apple had to consider such a scenario. Hmmmm. Will iTunes sync data? MobileMe? Or SOL?
