I voted "like 4e, think its doing well."
What objective indicators we have suggest good sales. Best seller lists, sales volume rankings, etc. Of course "selling well" is subjective, and none of those things conclusively prove a successful product, but as evidence goes they point in the direction of success. So at the most pessimistic, you could argue that the "selling well" hypothesis hasn't been conclusively proven, but you couldn't argue that the "selling poorly" hypothesis even has meaningful support.
Local stores are at best anecdotal, and since gamers tend to have a bit of a local culture, it isn't surprising that entire stores might go one way or another. In my area(s), one store seems to sell quite a lot of 4e products. I base that conclusion on their tendency to not have 4e products in stock when you ask for them, because someone else already bought them. Fortunately they have a restock rate of under a week delay, and most of what I want are adventures, so waiting isn't a big deal for me. The other store seems to sell 4e products, but not at any particular speed. The first store is mostly a board gaming and roleplaying gaming store, and has a lot of tables and some active 4e games. The second store is mostly a wargaming store, and also has a lot of tables, but no chairs because the tables are for wargamers who need to stand to hover over everything. The second store serves an older clientelle- more middle aged, while the first store tends to serve people in their 20s.
And of course the DDI throws a wrench in any calculations anyways. There are a TON of books I haven't purchased because I can get them online through a service I already paid for. I assume that, net, WotC makes money on the DDI, even though it trades off a bit with book sales.
