There is a lot I should probably read one day but didn't feel like it yet:
S. King's stuff (haven't read anything by him yet), Wheel of Time, Brandon's Stormlight Archive, some of the Paolini's newer books (after Inheritance cycle), more of Laundry Files by Stross, more of Pratchett's Disc World (so much more I haven't read yet).
Though presently, something by Asimov might be my next pick
