Mobile chips are getting very powerful, but where are the mobile games that demand that power?
Infinity Blade 1 - 3 and a few other impressive mobile games really pushed the envelope on the iPad 1 + 2 / iPhone 4 + 4S, but why should I replace my iPad Air 1 with a much faster iPad Air 3, if the Air 1 can still run any iOS game? BioShock has been pulled from the AppStore, the prettiest remaining iOS game I can think of (Modern Combat 5, even if it's almost 2 years old) runs fine and there are no hardware stressing iOS games on the horizon.
Without Tegra-exclusive ports (I'd love to try Half-Life 2, Doom BFG or The Talos Principle on my Z5 compact) Modern Combat 5 seems also to be the most demanding Android game for MOBILE devices with no new hardware stressing games for the PlayStore announced.
Tegra X1 exclusive games can't be counted as mobile versions as long as the only way to play them is on the Shield TV (power consumption while gaming 19.4 Watt according to Anandtech + power for the display). So there are no mobile games yet (and none in the near future) that can keep up graphically with 360 and PS3 games like The Last of Us, God of War 3, Gears of War 3, Halo 4, GTA V, MGS 5, Rise of the Tomb Raider or similar games. Mobile games/ports "in your pocket" at PS4/XBO fidelity are even farther away.
