Let's get the facts (and speculations?) straight...
There is no indication the Su-17 from OctopusG is for DCS, they also have some aircraft for other sims. And as far as I know, OctopusG is a 3D modeller for the most part, and they should be working on La-5 right now anyway.
Magnitude3 (The team SVKSniper is in contact with?) has already been teasing Su-17 for quite a while. Ultimately, we don't know if either project is approved by ED, but my money is on Magnitude3.
