They seem to be going to the 2e sales model where the core books drive sales of campaign supplements, rather than the 3e model where supplements drove sales of the core books. Which is odd given that TSR nearly went under during the 2e days and WoTC made plenty of cash from 3e. The fact is that a group only needs one box set, usually bought by the GM, but everyone like to have their own rulebooks. I'm hoping they do well, but I think they may have backed the wrong pony.
I think that comparison is a little too oversimplified: TSR died for two main reasons: Not listening to their audience, and overcompensating for market trends. When they did have a success, they overestimated print runs of things; when they went a new direction, they did no market or customer surveys. If they can do this, especially in this app-driven, subscription-based, tie-in world we live in, I think it's a decent plan with a good chance for success, IF they can continue to bring value.
Also, 3ed was a huge success, but sales began to taper off after 2003 or so, according to various pundits like Adkison and Dancey, and listening to some of the FLGS managers who have chimed in on various boards. That plus Hasbro's strategy at the time of only measuring performance by product line than by brand was very troublesome for WotC. If they are doing this, sounds like Hasbro has changed their tune on how they measure success again.
