Apparently this is also how Sony would like to approach the directing side of the project...they don't want to bring back original series director Ivan Reitman to helm the new installment, but rather would like to bring on a younger director a la the same arrangement Sony made to bring on Marc Webb for the new Spider-Man franchise. 

dudes are old. and theyve hit every roadblock already.
now that being said, Ghostbusters 2 came out, and a little 
late. it was exceptional. anything past that, in particular both
cartoon series, the video game, and the IDW comic books 
(more on those from me soon, trust me) has been excellent.
on that basis i give it at least the chance of hope. i also think
Reitman's good for it, and most of those guys listed will do this
anyways as they all need the cash and the screentime, maybe with
the exception of Ernie who you didnt list as being indecisive.
I would never expect it to be the first film though, in fact i would hope
for something entirely new. and if it flops im okay with that on the basis they 
finally tried it at the very least, so there wont be anymore wondering about it.
lastly i think their best bet would be CGI, though doubt they would.

Please don't f this movie up!

Actually, I saw the actors not long ago on TV and they honestly looked the same to me, so maybe they can play them again. Not that it would matter to me.
 
I thought My Super Ex-Girlfriend was one of the best non-comic quasi-superhero movies I've seen yet, as far as those things go. It was quite well made and entertaining. Some critics rapped it because it was funny, but it was surely meant to be funny. But, then, these things could use a few laughs. It was certainly better than Ghostbusters. 
 
Between the two, I'd like to see them revisit My Super Ex-Girlfriend than Ghostbusters.

Ah, ghostbusters. One of the few films from my childhood that has stood the test of time and does not suck the proverbial (like the Three Amigos and the Wizard etc). I really, really hope this gets made and as Catmanexe said, if it flops then at least they made the effort. But sounds like this is going to one long hard slog to get it made

i hope so
