I mean, what studios do they still have? What's their manpower? All of their talent has left, and their focus has shifted to mobile and pachinko. Their attempts to try and bring back something more substantial have ended up in disaster. The best they can do is to license their IPs, to live off of remasters/remakes and others' talents.

To my knowledge there has never been a game they made I was interested in, so I don't know.

Didn't they make that really successful Switch party game?

Konami still makes a lot of money. They won't be bought unless they really want to sell.

I'd love it if they get bought tbh, probably wont happens cause they are still very profitable as far as I know, but it'd be great, just to have someone else actually do something with their dormant IPs, some which are fantastic. If Sony could just go ahead and buy Konami and Sega, that'd be great.

I only care if Konami mismanages Yugioh. Right now they are doing a good job so I don't want them bought.

Konami is a pretty large company for whom gaming was only a part. The gaming is just what they're known for in the West.

They're a holding company now. No one should buy them as they don't really have studios anymore. If anyone were to buy them it should be a 3rd party publisher who plans to revive old IPs and just keep the Konami name as a brand but the actual company should be put down.

Konami still has some worthwhile IP's but no development teams.

Metal Gear Solid, Castlevania, Silent Hill, PES, YuGiOh are all valuable IP's, and with the exception of PES, have multimedia utility. In the case of YuGiOh, it's a massive mobile game with Duel Links having over 150M downloads, and the recently released Master Duel having 20M downloads. However, aside from that and Metal Gear Solid, it is hard to gauge how successful Konami's marquee IP's would be in this day and age, but they have potential to be huge. 

Are they though?  Duel Links seems to be in decline.  Master Duel is still kind of in the honeymoon phase, so we have to see what happens there.
