The above image looks closest to 24DMU (Digital Mock-Up).
Although previous images representing the F-3 in earlier official documents tented to look like the other DMUs, particularly 26DMU. So of course the latest image could still be just an image place holder. But still, its the latest and is besides actual budget being allocated to its air-frame development.
