Exactly. Spot on TB.
Perhaps it is just us though, I mean think about it; they can't do a complete rewrite of the game every year. You play a game like MGS, it's great, you play it again in two years time and it's a totally different animal, same characters but a totally different world with totally different things to do and ways of interacting. You can't do that in a football game, it has to have the same teams and a ball.
But saying that, FIFA 07 on the 360 (sorry, don't shoot me) has been completely reworked and is excellent. But saying that, Football Manager is a game that can't be rewritten from scratch and yet that is excellent every year. But, FM is better every year for one reason; the new features they add give you a lot more power to shape your games. PES gives you a new stepover and about ten online issues.
What annoys me is that they don't even add new teams, which admittedly isn't as important as gameplay, but it gives you more to do and it's a start; but they just cannot be arsed (every other football game includes the lower leagues from around the world now, even Japanese ones such as Sega's World Football Climax, so the excuse of "Japan don't want that" loses it's power). The price of an extra few researchers isn't going to bankrupt them and it would make a better game. But they're not bothered, even if it means keeping up with the competition, because they know their game now has a following and will sell regardless. Konami are the new EA.
To copy what TB has said, there's just not enough difference between each version; I don't sit down and go "oh wow, that's new, wow I couldn't do that before". It's the same. You have mates over and you realise even more that you're playing the same game you have been for years. There's no extra control, there's no extra competitions to win or things to do; it's the same game, the same gameplay. With a new set of animations and shinier graphics - which is what I hate, and the reason I stopped buying FIFA for ten years. I'll say it again, Konami really are the new EA.
If they could just improve one "important" element then it would make the game a hit again; perhaps fixing the way they seem to run on rails, improving on the lack of control you have (again, sorry chaps, don't shoot, but if you download the FIFA 07 demo for the 360, you can witness how you can make your players move when you press the stick, rather than ten minutes later - I wonder what Konami are doing over in Japan all year).
Nothing fundamental is changing. If they released one game every year, or even every two years, then they might be able to concentrate a lot more and make a hugely better game. But of course, Konami are a company, and £50x3 per customer each year is always going to be better than £50x1 per customer each year.
I also agree with what TB said about the places making the football games, to an extent. That's not being racist or anything (gulp); but the European market will want different things. I don't know anyone who could argue against adding lower leagues, making the Master League less about fantasy or at least giving you more options (Castolo and credits out, random English YTS players and cash in please)... Both of those involve adding to the researchers and adding to the programmers and don't involve taking time away from programming the gameplay. So everything could improve. But they only care about one market - we get a port, and it sells well, so they're not going to change anything.
I personally think the only time we're going to see a game as fun as PES used to be is if an up-and-coming European team of programmers pop up and beat them at their own game. But in today's world of next-to-no games companies surviving next to EA, it's not bloody likely. The only team out there at the moment with a chance is Sony's This Is Football studio. And they're after both markets, trying to make a half-way-house between PES and FIFA. So they're doomed to fail from the start ("Jack of all trades, master of none" - you're never going to succeed trying to do two totally different things at once - you can't scratch your balls and hit a 300-yard drive at the same time).
Mind you, it's been a long time since their last game, so maybe they've been working away on making a half-decent game. Who knows.
