They are maybe lying, but one of their latest tweets talks about a waiting list with over 100.000 people waiting for a Ledger Stax. Even if half of that is true, it's still a lot.
Problem is that ledger can't manufacture that much Stax devices and they already had to delay a lot because of faulty screen design.I think that Lixin Liu (owner of Keystone) talked about that in much more details on twitter, and he suspects that ledger Flex is just replacement for Stax.
Maybe ledger is just going to send Flex to everyone who ordered Stax and send refunds for price difference.

I can't believe Ledger had the audacity to release another overpriced product while some of Stax's batch 2 orders are still in limbo and to add salt to the wound, it appears that there's no difference between the BTC edition of Flex and the normal one [apart from its color (SMH)]!
Maybe this is all connected like I mentioned in my pervious reply.Let's see what happens in next few weeks.
We bought one immediately for testing.
I can't wait to read test reviews 
Stax was another BIG fail for ledger in every way, Flex is just their attempt to save the last tiny bit of respect they have left.
