***After some recent additions thanks to Urban Waste and Boss Tycoon, I decided to repost this in an amended form***
A different picture of the Free-Soled Flyknit was posted. The photo you posted is by far the best one.
After looking at the Flyknit Collective pictures again, I noticed that there is another upper and sole that I had not seen in the previous times I viewed the photo's. So far the releases to the public have been:
Flyknit Trainer - Lunar Sole (HTM)
Flyknit Trainer - Trainer Sole
Flyknit Racer
The other flyknit shoes that we know of but have not see a release are:
Flyknit Trainer Chukka with Lunar Racer sole
The really thin, porous mid with lunar sole
And the Flyknit with the Free sole
Which at first I thought was just a Flyknit Trainer upper with a free sole, but upon further inspection, it is a completely different upper.
Look at the toebox of the white/black stripe upper and compare it to the toe box of the Flyknit Trainer. They are different
There is also another Flyknit shoe with a completely different sole: The orange shoe which looks like an alternate Racer with a Lunar ribbed-type sole. Almost as if the sole is a combination of the current Racer sole and the Lunar sole
So it looks like we have more Flyknit technology to possibly look forward to.
Here is a recap of the models we have seen so far:
Released:
Flyknit Racer
Flyknit Trainer - Lunar Sole (HTM)
Flyknit Trainer - Trainer Sole
Upcoming Release:
Flyknit Lunar Chukka
Flyknit Lunar 1 (LG4 sole)

***UPDATE***
Now after seeing the photo posted by Boss Tycoon, I see that their are two different thin porous uppers:
The back round shoe is the Flyknit Racer really thin, porous mid with lunar sole
The fore ground shoe is the Flyknit Trainer really thin, porous low with lunar sole
Also, thanks to Urban Waste, we have seen the Flyknit Racer with lunar sole
Then there are two more versions of the Trainer upper:
The block toebox (making up a name)
And the open toebox (making up a name)
