While Apple's ensured all of its home-baked apps are making the most of the new iPad's retina display and new A5X chipset, it also had a handful of third-party app developers ready to show what the new hardware's capable. First up was Namco, who revealed the iOS-exclusive SkyGamblers, an Ace Combat-styled jet combat simulator. There looks to be a whole load of detail crammed into both the plane models and background -- something all those extra pixels can certainly help with and something we'll want to take a closer look at when it lands later this month. Taking a different approach, Autodesk's SketchBook app took the opportunity to show off the level of detail its sketches were now capable of, alongside a new engine for the ink. Now, we're not exactly sure what that entails, but we're sure it's going to make our works of art really zing. The app can even export images larger than 100 megapixels and will be out in April. Finally, Infinity Blade developers Epic Games took to the stage to unveil Dungeons -- the next iteration of the swiping and slashing gladiatorial battler. It appears the battle system has been recast once again and HDR lighting ensures the game will arrive dripping in optical honey. We'll be taking up swords to get a hands-on with these very soon.

Update: We've just added the trailer to the next chunk of the Infinity Blade saga. It's right after the break.
