Is it the graphics which look promising? Graphical improvments are the easiest areas to improve on each generation- more artists, larger budgets, more development resources. The Catch-22 is that with larger costs, the game developer needs to recop thier investments, that means the chances are the games utilizing them still go the way of your generic first person shooter, making the game still not really that much more exciting than the previous one, albeit with better graphics. More artists doesn't necessarily improve other areas, it doesn't necessarily improve upon the achilles' heel of all computer games- you'll still face a dumb computer opponent that will never make decisions which reflect human opponents. These development budgets are getting so large to the point where they rival those of small movies, that's why your bigger companies like EA are the ones who can afford to keep putting them out there. They take the risks to make these games with all the new graphics, so their investors want the game to appeal to the broadest audience possible- usually that means twitch action, hit points, medi-kits, a game that really plays more like an interactive movie on rails than rewards players patience and inventive strategy.
Furthermore, the conceit of these games always tend to focus on small unit commando type action- there's not enough personal computing power or development resources to bridge that gap between battalion to division sized operations, relying on the very fact of exploitable computer bots to deliver thrills by allowing the player to single handedly destroying dozens of enemies and should be getting the MOH each and every mission rather than re-creating a real war with typical maneuver elements.
