Actually, I disagree with the 1st, 3rd, and 5th points as being signs of what you label them to be. One of my biggest gripes with WotC/Hasbro and their management of the D&D brand is the fact that the layoffs in their rpg department that happened after I left came within 12 months of the launch of 3rd edition, which was massively successful. Instead of getting the bonuses they deserved, those people got laid off. Because the success of 3E made so little difference to WotC, let alone Hasbro, in terms of overall success.
Further, the selling of the D&D brand would indicate that someone felt it was worth pursuing, and thus could mean extreme success for D&D. (Remember, Hasbro bought WotC when WotC was at its peak.)
For what it's worth, I've heard little of the sales of 3.5, but what little I've heard is good. 3.5 hasn't sold as well as 3.0, but then no one thought it would, and that shouldn't be a measure of its success or failure. Personally, I think the real success or failure of 3.5 won't be measurable for at least another year, when its release--and subsequent products' releases--can be measured against the decrease in sales of long term sellers, like the splatbooks.
