Not really. Being ambushed with "bacon is extra" might well be enough of a nasty surprise to sour the whole breakfast experience - and that regardless of how much extra it is, or how crispy the bacon turns out to be.
2e to 3e didn't have one, unless you count Bane's return. Certainly, nothing in the level of ToT, Spellplague, or Sundering...I think RSEs are silly, but it's a tradition at this point. Every time you introduce a new edition of D&D, you have to blow up the Forgotten Realms. It's just what you do.
But to run with the analogy....imagine the bacon got to the table and then said "hey, I cost extra and I'm really tasty and delicious, but also high in fat content"...if someone then decided to get the bacon, wouldn't that be their choice?
Well, that's a valid response when determining whether you feel the breakfast is good or not by your own standards. But when you're putting a review together, you have a responsibility to deal in more than just your own personal opinion.
For instance, I'm not the sort of person who gets bothered by paying more for bacon if it's good enough bacon -- but if your review just says 'bacon extra -- 2 stars'
Mearls is on record as saying that too many books, of any sort, hurts D&D. Do you think he's lying?
Let's not put this on Hasbro's doorstep. Hasbro has nothing to do with this. Wizards of the Coast? Sure. They have budgets on how much they give to the D&D department... but saying Hasbro executives are concerned about the money spent on D&D is like saying they are concerned about how much the Nerf folks are spending on nerf shooters versus nerf balls. The only people who care about that level of detail are those who run the Nerf brand.
2e to 3e didn't have one, unless you count Bane's return. Certainly, nothing in the level of ToT, Spellplague, or Sundering...
