There is currently no news on the F400. Not every RealSense product that is developed by Intel ends up being released, so it is best to consider them as not existing until they are actually available to purchase.
You can read more about the F400 at the Intel promotional site below. As I said, in-development products announced by Intel are not guaranteed to be released, so please bear that in mind and do not make future plans based around them.
Regarding the images: the second from bottom one seems to be an F400 module, judging from Figure 8 in the paper. The longer board above that has lenses that match up to an image of the casing of the Vision Processor D4m (the Vision Processor for mobiles) on the Solutions page. I don't know what the bottomost one is. Tracking Module T260, probably.
