But there is no more joy with Konami because they don't make any games anymore......unless you're referring to the joy of pachinko lol :P

Contra is the game with the machos and Rambos. 

They're really not, they whole company as a whole is worth around 3 billion and the gaming division makes up a minority stake. 

I'd agree but in Konami's case they're just not using their ips and have no interest in doing so. Any company willing to buy and develop for those ip's would be a win for gamers, buying an active developer like Square, Capcom ect is different. 

Is Metal Gear not a big enough name for you? Kojima can either still work on new titles, while Metal Gear handed to a Sony studio, and that's 2 AAA games right there. How about Silent Hill that makes a lot of noise from the PT demo. Still nothing as big as Bethesda buy, but that's a 7.5billion price tag. 

I don't know if Konami would be good enough. If they do, M$ would buy SE or Capcom.

I highly doubt that SE would sell to MS. Capcom...possibly. Square, if they were going to, would probably sell to another Japanese publisher or something. Another thing, just because MS has tons of money doesn't mean they can just go buy studios left and right. They've acquired some big studios already. I don't see Sony doing that either to a lesser extent. Someone mentioned Platinum Games for Sony to buy. That's certainly not happening. If they would sell to anyone, it would be Nintendo. 

The Japanese government would never approve the acquisition by a American company

Free Suikoden !
But to be real,taking over their ip's is not like taking over good studios that can make those ip's.

This is essentially damage control. And I love it.
