New MGS Games to Accompany MGS4?

Will there be any more Metal Gear games before or after Metal Gear Solid 4: Guns Of The Patriots?

Thats the question on many fans minds as Kojima Productions work long and hard on MGS4.

Beings as there are two comics out covering Metal Gear Solid and Metal Gear Solid 2: Sons Of Liberty, the artwork in both comics were done by Ashley Wood and since then the 1st comic has been turned into a Digital Graphic Novel on the PSP, so the fans are now wondering if Hideo Kojima and his team will be working on making another PSP game in the Metal Gear series, called Metal Gear Solid: Digital Graphic Novel 2, it will be based on Sons Of Liberty from the PS2 and be done using Ashley Wood's Artwork from the comic book.

Also on people's minds is another game for the PSP, thats right it's Metal Gear Solid: Portable Ops, Ryan Payton has started on a couple of occassions that if Portable Ops is a success then he and Hideo Kojima would consider doing sequels to Portable Ops and consider the story of Big Boss, these would be in games like Portable Ops 2 and even maybe Portable Ops 3.

But hold on a minute therr are also other consoles out that have either not had a Metal Gear game yet or havent had one for a while.
These consoles are Nintendo DS, Microsoft XBOX 360, Windows Vista and Nintendo Wii.

As the fans all know, Microsft have had Metal Gear games in the past, they had the PSOne versions of Metal Gear Solid and VR Missions on the PC, then a few years after this they had Metal Gear Solid 2: Substance for the PC and the original XBOX console.
But Microsoft havent had a Metal Gear game on Windows Vista yet, so that might be announced in the future.

Also up for consideration is a Metal Gear game on the Nintendo DS using it's innovative touch screen, there is also the Nintendo Wii and its controllers with motion sensors, it would be interesting to see how a Metal Gear game would work on these new consoles.
