All that said, their Shield handheld console looks pretty spectacular, if vaporous.
5" ~retinesque~ touchscreen clamshelled onto a full-size game controller with all the bells and whistles. Outrageously powerful, has HDMI, USB, headphones, and holds a 5-10 hour charge. Runs pure Android with full Google Play access and a specially curated library built for the console itself. Can also wirelessly stream games off of a PC, including from Steam Big Picture. Cloud storage of game state comes free.
Not announced: price, storage, availability, who's making it, sales channels, or anything. So whatever. But this -is- the Sony PSP slayer, and it is another sign that all roads lead to Android+OpenGL ES on ARM as the future default game platform.
