I guess Fx had an agreement with Clove as a retailer for their device.
There's a lot of stuff that appears on the Clove site before it hits the shelves of network retailers. Clove may have made some investment in the development of the Pro1.
Understandably people are going to be disappointed that retailers are being supplied before the backers.

Received mine just now.
Initially I'm impressed with the build quality and professional packaging.
Powered it up, skipped all the "Sign up for Google This and Google That"
I'm finding the curved screen makes handling a little awkward which makes it difficult to pick it up or work the slider without starting one of the shortcuts or widgets on screen. I'll have to work out a snazzy move to do the slider thing.
Finger print scanner seems to be a bit hit and miss, but I guess that's down to the fact that I'm used to using the Xperia X scanner.
Personally I can't see it developing as big a cult following as "The Beast", but you never know.

I just hope you guys that are still waiting get yours sooner than later.
I believe Fx have sorted the backers into batches and as they come in from the factory they're going out in batches to the customers assigned to that batch. I have also read that there was a problem with some screens which caused a delay so the factory upped production to cover the backlog.
