I think mobile games may have more advance features like better graphics and sound than current handheld consoles like the Nintendo 3DS and PSP Vita in the future now that there are Google Android emulators like Bluestacks and operating systems like Remix OS which let you run mobile games at faster speeds on a powerful Gaming PC.
Some mobile game makers, and mod makers may see that there are users playing their games on very powerful computers, and devices and create mods to make a mobile game's graphics look nicer when played on a powerful PC, faster smartphone like the iPhone 7, or tablet like the iPad Pro or Microsoft Surfacebook tablet which has a lot of storage, and faster CPU and video chips which can handle higher quality video games at higher resolutions like 720P and above.
