The general plan for now is to produce the kickstarter units as you've seen in the notes. We added an RGB led since then but no more changes.
Looks like we will try very hard for a version 1.1 which will be selling after kickstarter and preorders... I'm going to try and do an SD card and IR communication.
After that looking at Arduboy 2 which will switch to a 32 bit ARM m-0 with bluetooth potentially. But to be honest it may be more attractive to spend the time and energy to drive the cost of the original hardware down.
Frankly I don't want to compete directly with other game consoles, but at the same time I can't resist the urge to make a really badass game console just for fun. That's how I got here in the first place so expect to see something. I will likely build prototypes of just about everything and now that we have such an awesome community then it's easy to build maybe 20-50 units of the prototypes and sell them in the store.
Also am planning lots of special editions of the current hardware. Keep an eye out for Ardugirl, Arduboy Black, and Arduboy Princess editions!
