No, the GTA04A5 will keep the Neo's exterior as it is.

It is still a motherboard replacement.

But as before you may be able to design your own case around it.

Initially we tried with the Telit modems but they were not flat enough
and we would have had to sacrifice the speaker (handsfree).

Fortunately we found the GTM601 which is used in the GTA04A1-A4.

They also have Qualcomm inside.

The same holds with the Cinterion PxS8 modules. Documentation is
also available w/o problems.

We are currently evaluating all these options, but there are technical
and commercial aspects to consider. E.g. the Telit xE910 modems
are 10% thicker and likely still too thick.

There is no plan to change the CPU since the OMAP3/DM3730 is still
the best mobile processor that can easily be purchased in small
quantities. And (despite the GPU) it is very well documented and
supported by mainline linux.

So please don't expect a wonder to happen... Just small steps and
improvements.
