I like Chicken!!!!!
But serious answer, from a business POV the better option would be for Konami to license those IP out to other publishers, then they get a constant stream of money from the sales of those games.
Selling off IPs may net a lot of capital initially, but licensing out those properties to other companies means they'll probably make more money over time.
If they decide to stay away from the 3rd party AAA development business they still make a huge amount of money with very little effort on their part, but they can still return to that space in the future if they later decide that's what they want.
