I can tell you the answer to #1 & #2 from @Kaled:
1- Unity contains Solar, Turok and Magnus in key roles. They'd have to pay royalties to reprint that. Don't look for that to happen.
2- No, no they are not going to license Magnus, Turok or Solar
Prior management(Dinesh) made it clear they would not but left it open if they could wholly buy those characters they'd look at it.
New management is clearly making their focus to get the IPs more into public consciousness via other media. Bloodshot w/Vin Diesel starts filming 8/3. They aren't going to burn capital on licensing characters they can't own and then market.
