PocketGamer.biz says that Apple is planning a dedicated fiefdom within the iTunes Store for "premium" games that cost $19.99. The section would be restricted to large publishers only—think Sega and EA. They've got no details on a launch date or which publishers are involved, only the educated guess that WWDC in June is the natural time and place to kick it off. If true, it means that Apple is more serious than ever about the iPhone and iPod Touch as a legit gaming platform, and that developers are working on more complex games closer to what's available on the DS and PSP. The iPhone has the horsepower to compete, sitting between the two in a dick-measuring contest, and developers have now had enough time to get comfortable with the platform to deliver legit truly gamer-worthy titles. But there are a ton of challenges to developing games more like the ones we see on the DS and PSP. The technical ones—battery life, limits of the dev kit , expected behavior of apps—might not even be the most challenging. The App Store is a 99-cent economy. Even if publishers do deliver DS-worthy games, people might not buy them. Segregating these premium games into their own section might break some of that user mentality—indeed, it's the reason having a separate section makes sense—but a $19.99 iPhone game still sounds like a tough sell.
