I know what you mean about the 3rd Robocop flick,it was pretty shit as you said. There were also a few Robocop made for video films,but I haven't seen them yet.
I heard about the remake,maybe Robo just needs a fresh new start,and you don't see that many sci fi movie remakes except for Planet of the Apes,and there have been plenty of horror remakes,(Halloween is going to be the latest.)
And yeah,it seems pretty strange and kinda whacked they would try to make a new version of something that dates back only to the 80's..
Either way,who knows maybe the next Robomovie will be better than the last one.
Another thing about Robocop,he's gonna be in the most unlikely of places..a fan film..well,what I mean is...check this out. www.aviatorpictures.com
