Just gonna point something out, all of the sequels you listed came out fairly close to the original movie. Alien to Aliens and Terminator was the largest difference, at 7 years, but the others were 3 and 5 (Indiana Jones), 1 and 1 (LOTR), 3 (Star Wars), 3 (Star Trek), 3 (Batman Begins). But BladeRunner 2 will be made at least 30 years after the original.
You've kind of missed my point and focused on inconsequential details. Just to respond to your comment though - here are some examples of good sequels/remakes with a larger gap in time:
Batman Begins (2005) - Batman and Robin (1997) - 8 years
The Fly (1986) - The Fly (1958) - 28 years
The Thing (1982) - The Thing from Another World (1951) - 31 years
Scarface (1983) - Scarface (1932) - 51 years
This is entirely besides the point. It's completely possible to revisit a universe and do a successful job of it, the quality of the film comes down to the execution of the film maker.

We all saw what happened the last time Harrison Ford got involved in a project after over a decade of sitting on it.
There is no conclusive evidence that Harrison Ford is going to be in this movie, and furthermore you cannot blame him for the shortcomings of the abomination that was Indiana Jones and the Kingdom of the Crystal Skull. Additionally, just because he was in one bad follow up film does not mean that all other follow up films are doomed to failure.
