I agree with most of this. Indiana Jones and especially Jurassic Park trilogies would look awesome. Jaws would be cool as well. Also pretty much any Disney movie (including Aladdin) would be a welcome addition.

However, I think Titanic is one of the most overrated pieces of junk ever and absolutely hate the movie, thus no need for that. And, despite being a big Tarantino fan and Pulp Fiction being one of my favorites movies of all-time, I'm not too worried about that coming to blu-ray. I guess that's partly due to my not being at that point where I'm upgrading movies I already own from DVD to Bluray, especially not ones that provide no real awesome visual effects. Thus, since I obviously already own Pulp Fiction, I wouldn't buy a blu-ray. Though it would be cool for a release, just I'm not eager about it or anything. Not like the LotR or Matrix trilogies getting released, etc.

Some other cool ones would be something like Ben-Hur or Spartacus or Lawrence of Arabia (old epic movies like that). Some of the classic Hitchcock movies like Psycho or Rear Window or Vertigo, etc. The Big Lebowski would be cool, The Sting (one of my favorite movies again), Taxi Driver, Dog Day Afternoon. Any of the Disney movies, like you mentioned, Aladdin, Mulan, etc. What Dreams May Come, Suspiria, Who Framed Roger Rabbit?, Dick Tracy, Gettysburg, The Last Temptation of Christ and The Ten Commandments. I'm sure I could think of more, but there are some off the top of my head.

I'm really surprised those films haven't been released on Blue-ray.
Even tv shows are put on the format. Well I expect the Blue-ray upgrade soon.
And Titanic was a really good film.
