1. correct.

2. Just judging from the missing backlash one can quite securely claim that the preorders have all been delivered. The remaining deliveries must have been ordered "regulary" at a later point in time which is still possible if you like the black 6GB/128GB version for 718€ more than the blue 8GB/265GB for 606€ https://store.fxtec.com/product/fxtec-pro1/.

3. Despite the (XDA) marketing, it is not a new product but the smart move to get Pro¹/X sales going by advertising a core feature (open bootloader) to an audience that was not quite aware.

And yes, i am still drooling everyday over the Pro¹ and preordered an X just for the awesome blue and to not having to temper with my "Perfect sfos daily driver"¹ to test UBports and possibly Leste somewhen in the future.
