Well it's not much but it's a start... it seems a support page for the Nexus Droid/Prime has been found. While it doesn't provide much information, it shows that things are moving along ...
Rumored specifications call for an HD (1280x720) screen of 4.5" or possibly even 4.65" , a dual-core 1.5GHz processor, and Android 4.0 Ice Cream Sandwich. I suppose any news on this device is good news and shows there is definitely something going on.. you can check the model number on Samsungs support page Samsung for any further updates as we will also and if anything new pops up we will post it.
As for different model #s, supposedly one is global and one isn't. Also, there is speculation that one will be the Nexus and the other will be some other Samsung phone. Nothing is confirmed as of yet. Refer to story below for additional information.
