We not only plan these upgrade boards but also complete phones as a long term
goal. Maybe, even in a different and improved industrial design. And in some
years with a OMAP4 :)
Our team is currently evaluating options (3D printers, rapid prototyping, 3D cutting,
protomold, etc.) and trying to build prototypes, but did not yet come to conclusions.
So please give us some more time.

Well, it is "only" adding some minor components to the kit (antenna, battery, USB-charger,
vibramotor, earpiece, speakers) plus a set of plastic parts.
But plastics is quite a heavy challenge if you really want to do it without big
venture capital. Even larger than getting the PCBs shown in the photos...
The problem appears to be that the inexpensive rapid prototyping methods don't
have the required precision (0.1 mm, 0.5 mm wall thickness, etc.) and those with high
quality are prohibitively expensive.
Unless you, i.e. the community, is willing to do fixed pre-orders for a total of at least
The idea of having the community design different cases for the Neo 1973 and
Freerunner is quite old , but I think there was only one group to show up with
a "case extension" . This can be printed e.g. at Shapeways but is not stiff and
precise enough for daily use.
