It looks like I'm making an executive decision to stick with the same screen for the next arduboy, Arduboy Zero. Just for simplicity, cost and time reasons. The survey sitting with a difference of only 9% isn't enough to piss people off with another black and white, and it's pretty clear charging much more (which we would have to do) for color is probably the wrong move overall.
It's actually possible to keep the new version at the same price doing this, and we can add a lot of functionality.
And as several users have mentioned, the black and white is actually what makes Arduboy, Arduboy.
Most of the game creators complain about the lack of memory as opposed to bit depth. We have seen some amazing things in black and white, and I don't think we are done yet.
I'd love to do color one day... actually as many people have mentioned Pocket Chip kind of fills this area. I'd love to work with them on something like a Pocket Chip Lite that could look like something of Hackfuffels renderings:
But, as you can see would be probably twice the size of Arduboy, and so again... really deviating from the magic formula.
