MGS3 was designed to make particular use of the PS2's control features, such as its analog buttons; perhaps this is why it remains the only entry in the primary Solid series exclusive to a Playstation console. Although MGS and MGS2 were originally released as Playstation and PS2 exclusives, respectively, both were eventually ported to other platforms. If MGS4 depends upon console-specific features as Snake Eater does, it is conceivable that it will remain exclusive to the PS3. We will not be able to make such a prediction either until its release or upon the availability of more detailed gameplay information.
But it seems rather premature to declare an end to exclusive titles, even among the most expensive productions. Another factor to consider in the long-term is whether future console generations will provide increasingly diverse feature sets. The Nintendo Wii is an obvious current-gen example of this; whereas The Twin Snakes was brought to the Gamecube, it is difficult to see how the complex control scheme of an MGS game could be possible on the Wii. Exclusivity may be necessary for many titles on future, unknown platforms.
I can tell you that I do not yet own a PS3, and MGS4 will most likely be the title to make be buy one. How do I feel about having to buy a new and pricey console to get my hands on this game? How will I feel if, half a year later, one or more ports appear on other platforms? Well, a little ripped off, probably. Though there is an obvious and happy benefit to being "there" at the time of initial release, it will seem a bit dishonest on the part of MGS4's producers if it turns out that, no, I did not in fact need to buy a PS3 to play the game. What about you?
One way or the other, system exclusivity is a good thing for any game. It ensures that the design of the gameplay is fundamentally tuned to the system's strengths, promising a harmony of technology and content: Playing a game on the system it was expressly developed for provides the best possible experience for that particular title. Furthermore, system-exclusive production fosters innovation as developers make the most of a platform's strengths. In the end, it may be better for MGS and videogames on the whole if gamers like me happily lighten their wallets in support of MGS4 and the PS3.
Well, I'll think about it, at least.
