Is this proof that online will soon be the only way for D&D, or that only the online users opinion matters?
Not just online, but in gaming stores only. The Encounters system has a lot of adventures and "rewards" in the form of friggin' supplements and adventures. Stuff I would LOVE to get myself but I can't because I don't want to play in a game store. It doesn't fit my schedule or my temperament (I curse a lot, like to make a lot of noise at the table, I like my games to last as long as it takes to finish or until everyone wants to go home, and I like being able to not allow some people to play in my games and not have to worry about the store owner mad because he/she loses a customer).
Everything seems to be focused on fancy online tools, board games, and adding crap to books that don't need to be in the books (like the friggin' tokens). All the content that should be in Dungeon is going to Encounters, they're more worried about the next shiny new tool than making the ones they have now work right, and Dragon has pretty much just become a dumping ground for "didn't make the cut" powers and feats and a few articles about what random Wizard employees do in their personal games.
I figure Wizards got probably $300 from me in D&D Minis, the various books, and my DDi subscription in 2008 and 2009. In 2010, I was focused on Shadowrun because my friends were interested in that so I canceled my DDi (a billing NIGHTMARE no one ever fixed so they still owe me $10). This year, even though I have a campaign starting soon, I think I'll probably be spending maybe $75 total the entire year - a few packs of those cards and the boxed set just so I can get the Deck of Many Things and let the rest collect dust on a shelf. I might get Heroes of Shadow/Monster Vault 2/Vile Darkness if I hear any of them have anything interesting, but I don't see myself getting two of them let alone all three.
Wizards, just do what you were doing. Give me minis, a PHB, a MM, an expansion book for a power source, a new campaign setting, and two or three adventure books a year. Dumb the stupid tiles, dump the tokens, fix DDi like it was before. Do that, and you'll get my money. I promise.
