D&D 3E/3.5 Will there be a "Die Vecna Die" equivalent for 3E-4E?

[wingsandsword]

'The Apocalypse Stone' was hugely fun (at least in my memory of 1999!). Never played Die Vecna, but (IIRC) it has a really bad reputation in some circles... Maybe for die-hard Greyhawkers..?

Die Vecna Die was a crossover between Greyhawk, Ravenloft, and Planescape that disrespected each setting.

In the old 2e multiverse, two of the most powerful entities of all were the Lady of Pain and the Dark Powers of Ravenloft, both were beings that within their respective realms of Sigil and Ravenloft were powerful enough to keep entire pantheons out and not even greater gods could do anything to affect their realms.

The Lady of Pain, strong enough to keep countless greater gods out of Sigil, by force if needed, in Die Vecna Die finds herself in mortal peril from Vecna, who has managed to escape Ravenloft by force, escaping the Dark Powers by raw skill at magic and is trying to seize control of Sigil in much the same way. Some PC's are needed to defeat Vecna and preserve the multiverse, but even if they succeed the most they can do is to minimize the damage Vecna has done to reality and the multiverse switches to 3e in the aftermath.

The very premise of the module violates key concepts of both Ravenloft and Planescape settings, and from what I've been told wasn't too faithful to Greyhawk either.
