Some updates on reddi from scurvixt:

so for button configuration, the only way you can change anything is by adding an attachment with buttons.
so you CAN have physical buttons if you really want them, but you'll need to buy the attachment separately.
i don't think you'll want to though because the touch buttons are really good. it doesn't feel exactly like physical buttons, but you can still push down and feel when they've been pressed because of the haptic feedback thing. if you run your fingers across them quickly, you wont feel the buttons, same as when the device is off... but that doesn't matter much because you'll very quickly get used to the positioning of the buttons. i'll admit, it does take a little bit to get used to it, but you'll forget about it after using it for a few hours.
As for the handheld, i dont really know. all I know of is the console, core gamepad(s) and the attachments. I'll update once i know more.
the price is lower, but that doesn't mean this isn't a powerful console. it may not exceed the ps4 (i don't know for sure), but it is definitely on the same level, if not, better than the xbone. that all doesn't really matter though,
the games that will be announced will make you forget about the console.
