As someone who grew up playing the TMNT, Xmen and Simpsons arcade games as well as playing Contra, Goemon(Mystical Ninja) Gradius, Suikoden, MGS and tons of other games on consoles, it makes me sad to see Konami imploding like this. Fuck their gambling bullshit; I just want good games! I wish Kojima the best and hope he creates his own company/takes his team with him if he can't patch things up with Konami. I'd love to see another 2d Castlevania as well, whether it be Metroidvania style or old-school. Goemon hasn't gotten any love lately either.
edit: I have a Suikoden avatar and I forgot to mention that amazing series.(edited it in to the 1st paragraph) It's a very very niche series but I'd love to see another Suikoden, and it's not like they'd have to go big with it. Make it 2d like Suikoden 1-2; they've aged better than the polygonal PS2 games anyway with Suikoden 2 still looking really damn good.
