I agree, though I'm still thinking a "director's cut" of the games is feasible. A LOT was cut at the last minute in all the games. Modders restored some of it and it greatly opened up replayability.
Why do people not want to have their PS3s hooked up in 2020? They can't play most of their PS3 games or digital PS1(physical too)/PS2 games anywhere else and it's much better as a blu-ray player than a PS4, I don't see any reason why people are going to specifically avoid keeping them hooked. I can see your point regarding 360s since the One pretty much replaced it outright but the PS4 is no substitute for a PS3... at all.
People like to play games at 4k? 4K TVs only had a 30% market penetration as of last year and that's specifically in the USA which is one of the wealthiest markets around.
Fair enough but the average user doesn't buy or even care about DLC, sales are always much much lower than the actual game.
As someone who has the games on PC, this is true but having the 3rd game on Origin is hardly that inconvenient and the mods you're speaking of aren't hard to find at all but most PC players don't much care about playing shooters with a controller when the M+Kb is right there.
Well... all the reasons you cited are pretty damn niche and judging by the sales of the Bioshock and Borderlands collections, the investment it would take to get this done wouldn't be worth the return at all as I really doubt it would sell that much. I get what ou mean and of course it would be really cool to relive one of our favorites all dolled up for current gen stuff but I don't really see a thirst for this in the marketplace and I doubt it'd perform all that well either. I'd buy it to show support, but you seem to be overestimating the sales potential here, sadly.
