Yep, it's happening. I honestly don't know how to feel about this. Unlike most I actually liked Kingdom of the Crystal Skull (not as much as the previous movies, but still), and if there was one good thing about Force Awakens it was Ford proving he can still return to one of his old roles and make it work. On the other hand if the new movie turns out to be a bland, disney remake of Raiders of the Lost Ark, like Force Awakens was to Episode IV, then it's a waste of everyones time. I hope it turns out to be something good, something with balls and ideas, not just flashy "update" of a great classic.

it wil be a bland boring update of the temple of doom
just with nothing that made the temple of doom so good

No.

Indiana Jones and the Temple of Prune Juice

After Indy4 and SW7, I have little hope. :\

Kill me.

Indiana Jones and the Lost Viagra :P

Expect heavy product placement by AARP and The Scooter Store. Maybe ol' Indy will pitch a few reverse mortgages or something.

indiana jones and the walking rack of doom

Somehow I'm actually a little bit optimistic. Or perhaps I'm just desperate for a loving modern treatment of a childhood favorite, in light of March the third's abomination.

Will Harrison Ford brutally retire from the series in the same way he did for Star Wars ?

I cannot envision any way in which this could be a good Indy movie.

Why? I mean, I can get low expectations, but even if the chance is slight, I don't see a reason why it being good should be outright impossible.

Well it can't be worse than Temple of Doom. I just can't watch that movie.
