Edit: Sorry I didn't see you've played Guild Wars, I didn't think it was that time-intensive compared to WoW but I guess I'm wrong.(not played it much), I guess there is DDO.

City of Heroes/Villiains is pretty good for a casual player.  In 30 mins of play you can do a mission or two, depending on your archtype (class).   Plus has probably the best character customization around.

EQ2 has improved in the last year, but the sheer size of it may bother someone with limited time.  Occasionally you will have to take some time to get to Point A from Point B.  There are griffons for flight as in WoW, but they only help you get around a single zone.  This travel time is not nearly as bad as in EQ1 though.

Both games have free trials so I'd say give that a try.  Free is always good, I can afford free.

It takes a bit of getting used to coming off WoW, but with quicksaves and pausing... might fit your hectic lifestyle a bit better :)

Unfortunatly, I've never been able to find a demo of Oblivion, I still play for 1-2 hours now and then, but it's not my favorite game ever. But read the reviews, it's one of the highest ranking games lately, and don't just take my opinion on it :)

I have twin 11 week old boys and a 3y old daughter, so I empathize with your lack of time. I agree that EQ2 is a good choice, as there is always something you can do solo (I often jump on for 30m and to the broker, or travel around). I also concur that CoX is a great casaul MMO, give them both a try...

If you are going to give COH or COV a try.. I would get the Good vs. Evil eddition, has both games for the price of one.
Plus you only pay one monthly price !!!
Plus you get all the hero bennies from the villain side, like being able to enter into a supergroup base, and all the COV costume options as a hero! And the community is awesome!  You can allways find someone to play with even if it's for only like 30 min.
Getting ingame cash is simple. most lvl 50 make so much they just give it away!! And there is allmost allways a costume contest going on undet the Atlas Statue in Atlas Park, So make your toon look cool and it could pay off!
I jump on for an hour or so everyday, then back to GuildWars! Those are the 2 games I play.

I have tried WOW but I didn't care much for it to honest with you.
DDO was cool but like was stated earlier doesn't fell like an MMO much.

So my openion is COH/COV and Guildwars Nightfall. I like the henchmen option, I really don't need to team much with that game.

Best regards

EvE could be for you.....actually i think it might be ideal if you like the style of game eve is that is.

First of all while it is very corp [guild] oriented its demands on your time is up to you if you have to go just say in the corp chat " Need to be AFK see you later" or you could just log off and come bacl later. Also leveling wise is done in real time youy select a skill you want and it tells you how long before its learnt. No grinding no running around for mobs. its done in real time even if you are offline and asleep.

There is a free trial you can try it will at least give you an idea if this game is for you. For any further questions ask in the EvE forums on this site there are a ffew around usually who can help you.
