OpenMoko has set up a Wiki for its projects, including the Linux-based OpenMoko Neo1973. Plenty of information is already available on it.
The specs are pretty much what had been reported earlier. The Neo1973 will be powered by a 266MHz Samsung processor. It will come with a 2.8-inch VGA touch screen, 128MB RAM and 64MB ROM, AGPS (Assisted GPS), quad-band GSM/GPRS support, Bluetooth 2.0, a microSD slot and push email and PIM synchronization support.)
In terms of roadmap, the general release will be later than initially expected. A developer edition will be sold to developers from now until September with a general release then following. Pricing is expected to be in the $350 USD range. Openmoko also plans to unveil five additional Neo devices with different form factors.
In the US, Sprint and T-Mobile are the early favourites to be the carriers given that they are more open to open systems than Verizon and Cingular.
The Neo1973 will be manufactured by Taiwanese FIC (First International Computer, Inc.).
