I haven't been in the building at WotC for 18 months, and things change in business. So I'm making no claim to any inside information. But I am intimately familiar with both Hasbro's attitudes toward the IPs it owns, and D&D's performance history.
I believe in my heart of hearts that Hasbro has never considered, and will not consider, selling D&D.
I am not in a position to know with 100% certainty what Hasbro and WotC are up to with D&D. (And neither is anyone else outside of WotC, not even Ryan.) But this rumor floated a number of times, both openly among the gaming public, and quietly, within the industry, when I was in a position to know. It was always 100% bogus then, and I feel pretty safe saying it's 100% bogus now.
Oh, and I've seen Lurking Lidda's love child, and I can attest to the fact that it has considerably fewer than three heads.
