The answer is no. There is, frankly no need. These are, as Obi Wan would say not the rumors you are looking for. Move along. We, that is, the gaming community are not the targets of these rumors. I suspect, as was the case for the original rumors last year, unoffical of course, around Gen Con, the target of the rumors is none other than third part developers themselves.
Last year, I was told through that freelance writers were getting good hints that there was going to be a 4th edition and that it would not have the OGL attached to it. This year the rumors are stronger, and with Monte deciding that now is the time to get back to writing fiction, there may be a tremor in the third party d20 market. The long term prospects for d20 and OGL supplements is now severely in doubt.
To this extent, this might be the best of all possible worlds. It might mean that they are in fact working on 4E, (and thus the rumors, even Microsoft can't stop rumors on all their projects) but not at the rushed pace some people were fearing. They might be actually doing it right in terms of development. Or, as I suspect, they are leaking these rumors to squash the growing trend in low cost (and low price) electronic books. WOTC's own answer to the PDF is to offer their own at the outrageous price of a hard copy book, clearly indicating that they want to crush this new medium for gaming materials completely.
