I just received a Nokia Developer Newsletter, which contains this piece of information:
"How to request the Nokia N950 developer kit
To help prepare for the publishing of apps for the Nokia N9, a limited number of developer kits have been produced using the Nokia N950. This phone has a pre-release version of software for the Nokia N9 and some minor hardware differences (e.¬g. the Nokia N950 doesn’t have NFC). The Nokia N950 Developer Kit is available to qualifying Nokia Developer Launchpad members who have published apps to Ovi Store, or have started to develop their apps using Qt. If you wish to obtain one of these kits, please send your request to: nokia dot developer dot launchpad at nokia dot com.
The deadline for submitting requests is 31 July 2011."
