I don't think anyone would, as long as they don't get some of the stupid ridiculous voice actors from Oblivion. But, TESV will likely be a console game aswell, and consolers will be whining if they don't get all of what PC gamers get (Just look at how many complain due to the lack of a CS)
Aren't your stats a show of your skill? The fighter's guild is more likely to promote a large butch warrior than a skinny commoner. (Maybe everyone would have the same build, but only due to limitations)
Anyways, do you not count quests as tasks? The guild will know your skills once you've killed every bandit in a cave. Stat requirements makes sure they know you've got the awesomeness.
I don't mind the lack of a CS, but PC users would get far more angry than console users if they didn't have a CS. If any platform would have one game disk while the others have two, it would be the ps3. The ps3 uses blu-ray discs, and blu-ray discs can hold more information then DVDs. I wouldn't mind having two discs, but with the ps3 version, everything would be on one disc anyway.
Stat requirements are easy to reach in Morrowind. Also, in Oblivion:
1. The Fighter's Guild needs recruits, so I doubt they would be picky.
2. The Mages Guild may accept any character, but the Mages Guild requires you to several tasks and receive recommendations to obtain access to the Arcane University. The Arcane University is what offers the real benefits of the Mages Guild.
3. The Dark Brotherhood requires you to murder someone to contact them. Then, in order to join the Dark Brotherhood, you must kill a certain target and prove your commitment to the Dark Brotherhood, or you could kill Lucien and lose all hope of contacting the Dark Brotherhood again.
4. To join the Thieves Guild(which is basically made up of poor people trying to make a living), you must be caught for stealing or your must search a bit to find them. After finding them, you must prove you are a capable thief by completing a quest.
5. The Arena is just killing for entertainment. Owyn expects you to die from the beginning, but all the Arena is looking for is people to fight each other to the death. If you actually prove you are a capable fighter, you rise in rank and eventually gain some respect.
6. To join the Knights of the Nine, you must go on a pilgrimage.
7. To join the Court of Madness, you must find a way to get past the Gatekeeper.
Joining major factions in Oblivion may involve a quest in which you must prove your worth first. If one of those factions doesn't have such a quest, it may not allow you to get any actual benefits until you prove yourself, even though you joined them. If it doesn't have either of those(Fighter's Guild and the Arena), then the conditions of joining still makes sense.
