Obviously this message will contains *SPOILERS*.
I want to see a battle for power in the time after the Patriots. Snake must not be the main character, however he may be a supporting character who can be connected via codec. Playable character is a bit hard question: Raiden won't do as a ninja (probably too action-focused, though it could work). Johnny doesn't feel like a playable character. Meryl... Not a good idea. Even Otacon would be better. I suppose having a new playable character could be the best, though it would require VERY careful design.
The story will need to be better than in MGS4, preferably better than in MGS3 too. MGS2 would be on a good level but it could be simplified a bit to make it more accessible (but not too accessible). MGS3 and especially MGS4 have much in their stories but in the end, they are both very simple.
Gameplay must remain focused on stealth. MGS4 was way too action-oriented. It was advertised as having a choice but it felt pretty strange that both ways were effective, with the exception that stealth was slower. Sure, higher difficulty levels pretty much (but not completely) fixed this but it's just not MGS. It you want a shooter, get Killzone or GeoW or something like that. MGS is supposed to be stealth.
And finally... Add trophy support for MGS4 and get rid of the installs in MGS5.
Actually my final wish will be that Kojima will be able to do whatever he wants, and so far it seems that it's definitely not MGS. Yep, I hope it's not Kojima this time.
