Do they really want the Spiderman rights that bad now?

Sony Pictures maybe... I fail to see the interest Disney would have in the electronics business.

No corporation will ever buy the entirety of Sony no matter how low they cost or how big that company is. Here is the problem, by purchasing Sony as a whole, they're also taking responsibility for the ENTIRE debt of Sony. And Sony is one of the corporations with the biggest debt in the WORLD. In other words, it would never make business sense to any company even if Sony was given to them for free because their debt is at a point where it's a lot higher then all of their assets combined.

Disney might be interested in buying Sony pictures, but definitely not Sony as a whole.

Ehm no, disney makes less money than sony

It's not exactly unwise to tap into every marked there is, atleast when you are backed up by a lot of profitable divisions. It'a all about ending up with the biggest monopoly. the less you got to compete, the better. In the end in about 200 years, i can actual imagine a corporation ( we don't know about yet ) owning proximately 50% of the entire globe marked. That is a lot. The trick is to do this wisely. Keep building on the divisions that does greatly, remove it as soon as ( Like Vhs, when the DVD arrived ) and jump as fast as possible to the next thing to avoid a big carry load. I expect that is what happen to Sony and will happen to a lot of other companies. You becomes so big so fast, when the marked is gone, it's a free fall from there and you will need to hang on and try to find a new grip in the new marked. If Disney buys Sony picture and the other of the good Sony divisions, they got a stronger marked overall. And with the electronics of Sony, they can use that as a benefitial part of their other Divisions. Sony deals with cameras, Tv, Blu rays etc etc. there is a lot of potential there to cut the production cost on their profitable divisions they had from before.  If they make a new pixar movie, they will safe a lot of spendings from actually owning the rights for Blu-ray. The cameras can be a big part as well, if they are shooting movies and stuff. they don't have to pay for the extra fee.  Etc etc. In the long run, this can profit them more from their most profitable divisions as well as selling these products.  

Eh, Marvel being in charge of the Spiderman license will make Sony more money than Sony making the movie.

Columbia is a pretty terrible movie maker compared to Disney. I'm sure that Disney would love to be able to make Amazing Will Smith, James Franco, and Adam Sandler films 

Oh my, a God of War sing along, yeepee?

Sony doesn't own the bluray format. Both them and Disney are board members in the Blu-ray Disc Association. Also Sony TVs are there own business now. It would make no sense for Disney to buy the non Columbia films parts of Sony. Disney actively eliminated their inhouse game developers over the past few years. Or they were last time I checked.

For PlayStation, PLEASE NO.

For everything else that is used by Sony, sure.

Eh, you do understand that Sony has assets worth over 15 trillion yen! It's also a conglomerate. As Eddard Stark once said "one does not simply buy a multinational conglomerate."
