Size: Similar. If we have to increase it, it will not be much (maybe 1 - 2 mm to one side)
Clamshell design: Of course!
Full sized SD Card slots: I would like to keep these as well.
USB Ports: Sure thing!
Gaming Controls: Ummm...
Replaceable battery: Yep. I want to keep the exact same battery for various reasons.:
Nubs: Completely new ones. We already have some samples that are working so much better (best nubs I've ever seen).
LCD-Cable: While the current ones are good, they still fail too often in my opinion. With MIPI displays, we don't need LCD Cables anymore.
Case: The case will be completely designed and produced by one company in Europe. This will ensure a higher quality.
LCD: Better refresh rate, higher resolution (ideally 720p, but that's hard to get), size increased to 5"
Keyboard: Slightly improved layout, better feel, probably backlight
Wireless: Improved Wifi, but maybe also optional 3G/4G would be neat.
Speakers: We already have samples of much better speakers.
SoC: A more recent one, of course. And yes... we have the confirmation for one now, but I won't tell you
So, that's my basic idea - what do you think about that?
