I'm afraid I don't know what Sony is doing. Think about it. Why would they hold rights, to gain profit right? Well, as sad as it is, the sponge for GHostbusters 1, 2, REAL and Extreme is almost, if not already dry. There hasn't been to much more products out on the market to make the money. People are running out of things to buy. Now if sonynot selling, that I could see. GB3 is a a good chance to make hordes of money. Selling it off may give Sony a quick profit, but long-term sales after all the toys and shirts and what-not are out, the royalties would skyrocket for the lucky company who bought it. Thus leaveing Sony in the dirt…
What sony NEEDS to do is greenlight the project, soak the spong some more. That way, they can re-fresh the GB market and make more and more, why they are holding back I don't know, they're letting a good “product” go to waste. If they couldn't take care of it, they shouldn't of bought GB in the first place. Their negligence is hitting the fans each day. It's like they're teasing us by waving around the contract saying “Ha ha look what I got and no one can have it, let's put it 6 feet under and never worry about it again!” They should stop worrying about Microsoft's X-Box and focus on an area I pray Microsoft never touches, Movies.
On another note, getting LFD to do it would require a ton of paperwork, and probably be very costly, Lucas doesn't work for just anybody. (never seen LFD slapped on anything but SW, was it on Indiana Jones?)Fox could easily handle the project though.
In closing, Sony should either A.)quit letting BG die and try to puch for another movie, hell another cartoon, anything! or B.) Sell it for a ton of money and hopes the buyers never make that much, but will most likely happend. It boils down to Sony will have a chance to make money if they act. Which choice they make is up to them. If they just sit around, royalities won't pour in like they use to.
Sorry for going on so much, but I had to get my rather large two-cents out.
