If you like 
Jordan you prefer his superiors in epic fantasy like the aformentioned 
George R.R. Martin's  series 
A Song of Ice and Fire, a plamned 7 book series that includes thus far :
A Game of Thrones
A Clash of Kings
A Storm of Swords
A Feast for Crows  (coming out later this year)
Dance with Dragons  (forthcoming)
This is thus far IMHO the best seires ever written in epic fantasy (at this point).  Peerles characterization, peerless plot- almsot single handedly brought respectability to epic fantasy.
Steven Erikson  is writing a planned 10 book cycle his
 Malazan Book of the Fallen which includes:
Here are the titles:
Gardens of the Moon 
Deadhouse Gates 
Memories of Ice 
House of Chains 
Midnight Tides  
Bonehunters (forthcoming) 
Reapers Cale  (forthcoming) 
Toll of Hounds  (forthcoming) 
Dust of Dreams  (forthcoming) 
The Crippled God  (forthcoming)
This is one of the few high magic series I can stomach, perhaps the most extensive world building ever in a epic series, high magic, huge cast, and not ridiculously written.
There are also some 
Malazan novellas that were available by PS publishing writen by 
Erikson, entitled 
Blood Follows  and 
The Healthy Dead  . I think the PS novellas are out of print, but NightShade Books has reissued them. There is also a recently released novel entitled 
Night of Knives set in the Malazan universe written by Ian Cameron 
Esslemont, that chronicles some important events that occur before 
Gardens of the Moon  
R. Scott Bakker is IMHO goign to pull of teh best 
completed epci fnatasy sereis we have seen since teh late 70's (Patricia Mckillip's RIddlemaster series) in January, with his thrid and final book in his Pricne of Nothing series that includes:
The Darknesss That Comes Before
The Warrior Prophet
The Thousandfold Thought
