Indiana Jones is one of the greatest adventure movie characters ever created, and he's been perfectly portrayed by Harrison Ford. I love that this character exists, and I can't imagine what the world would be like without him. I'm excited for the prospect of another movie because with Disney and Lucasfilm more involved with it than George Lucas there's a good chance that another movie would be just as amazing as the first three. The reason I say that is because they are fans of the franchise just like they are of Star Wars, and from what I've seen and heard about Star Wars: Episode VII, I love the direction they are taking it. The team of people behind these movies have seen the mistakes Lucas has made, and I know they aren't going to repeat them. So yes, I believe that when they move forward with another Indiana Jones movie, they are going to give the fans a film they'll enjoy.
The poster art you see here comes from artist Mark McHaley, and it pays tribute to the first two Indiana Jones films. I'm sure the artist will release one for The Last Crusade in the near future, and when he does, I'll make sure to post it for you!
