Revised, not reviewed, Shadowlord. 
The MM2 and similar books will most likely not be revised, although some web-errata is very likely to appear that updates them to 3.5E.
If they sell well enough to warrant a reprinting, then WotC might revise them, but I doubt it - the costs most likely outweigh the benefit.
I'll go out on a limb here and say Monsters of Faerun will definitely not be revised. However, I expect a few monsters from it will be in the revised Monster Manual.
Cheers!
