I feel like it's very likely the range mechanic will be tied to existing range mechanics. Given that it's been 5+ years since FSD ranges broke the 20ly rule that Missions were built around, making it essentially nonsense, and PP 2.0 has gone with that rule again anyway despite both SCO and PP 2.0 being an opportunity to readjust it, they ain't gonna change it for colonisation.
So if you go with PP 2.0 lore (and by lore I mean retcon, see above!) if a Power can't even properly exert influence over more than 30 light years even though both systems have 1000 years of spacefaring and another 1000 years of naval colonisation under their belts... it feels quite likely colonisation isn't going to stretch over that 30ly limit either.
I suppose there are those weird expansion or emergency missions that crop up and I think the limit on those is about 200 ly? So mayyyyyybe we'll get 200ly?
