Some Greyhawk deities are making the leap as generic gods as well. I think their generic treatment may inform Greyhawk, but it does not supercede Greyhawk canon.

In a video interview, they noted, that while the "core" gods will be part of this mapless world that they are putting forth for 4E, individual campaigns will have their own gods. Greyhawk gods will not be going anywhere, and people playing in 4E Greyhawk will keep them, but recognizing some of the 4E design issues may be worthwhile. Is there a high priest of the summer wind? Do they need martial clerics?

The god issue is a mess. Core gods who are also Oerth gods who are also Toril gods...
I'm looking back to 1e for inspiration on generic clerics with a few deity-specific skills and abilities.
So as for the gods, points of light (mish mash pantheon), Greyhawk (Oerth pantheon), Faerun (Forgotten Realms pantheons...minus a few :p )
This doesn't mean that some of the Helm/Tyr weirdness will necessarily occur. Nor does it mean that a deity as prominent as Mystra will necessarily have to go. A general shakeup should be expected, however.
In addition to some cleanup work, we might see some plot-related changes in the pantheon, but that really depends on how far they advance Greyhawk's timeline and what happens in the interim.
Greyhawk appears to be less compatible with 4th edition than Eberron but more compatible than the Forgotten Realms, so something in between those two will likely occur.

Moradin, Garl Glittergold, Correllon Larethian, Lolth, etc, etc, etc.
There's a pdf full of greyhawk gods floating around, includes those allowed in LG plus the humanoid gods - it's very long!
Yeah you can download it from WotC's Living Greyhawk site. There might be a better source for Greyhawk deities out there, but I'm not aware of one. That document is also a good indication of why a general cleanup of the deities of Oerth might not be such a bad idea.
The Greyhawk gods are iconic. They've been around longer than most players. Pelor is a the most resonant image of goodness ever created by any RPG company. At the same time, no story of destruction and recklessness has ever been better told than that of Tharizdun. Greyhawk is teh great.

Not at all. Eberron banked all of its fluff on the Vancian Spell System. Now with the advent of At Will and Encounter powers that do not use components, Dragonmarks are lame. They'll need to rethink the way Dragonmarks work, if they work at all.
Why go to the house of healing when minor cures are At Will?

And this is something new? As Alter_Boy pointed out, "Moradin, Garl Glittergold, Correllon Larethian, Lolth, etc, etc, etc.". All of them in Greyhawk. And all of them in Forgotten Realms. Is it really so strange to see them in core, too? Nevermind that the Realms is packed full of numerous other gods which aren't unique to it. Like Tyr, Tyche, Oghma, Silvanus, the entire Mulhorandi Pantheon, and so on. It's pretty clear that many gods are worshipped on more then one world, and that's been the case very nearly the entirety of D&D's history.
At any rate, I don't see any need to go the FR route of actively pruning deities in mass deicide, though I can see some shuffling around in the ranks and some new promotions and additions. You could just leave the more fringe gods for Dragon articles to flesh out later (if the interest is there).
