That is surprising, coming from the company that thought Resident Evil 6 "failed to meet expectations" after selling how much, 6 million units? It was a huge number.
Maybe they don't expect as much from their "lesser" franchises. That would be beneficial to DMC5. Though seeing as Dragon's Dogma failed to become a franchise, and how DD Online hasn't even been planned to release in the west, I think Capcom has changed their minds about the solidity of DD's sales.
They're working on DD2, so how has it 'failed to become a franchise'? DD will most likely become a franchise with at least three entries. I don't know Capcom's reason for not releasing it in the west, but I doubt that Capcom suddenly changed their minds, and decided DD1's sales were not good... I don't see any reason why they would go back on what they said.
It's also been reported that there is a chance DD Online will be released in the west depending on the fans' reception. So my guess is that Capcom decided to change some things about Dragon's Dogma. Maybe the characters are more 'Japanesey', or maybe the story is. There's probably something they changed to make DD appeal to the eastern market more. Financially, it makes sense when you think about it: DD was always kind of Japanesey, which isn't that appealing to westerners. So Capcom's logic is to stop making DD appeal to westerners, but mostly (if not fully) on the eastern market, to squeeze as much money from it as possible.
The reason why they said RE6 didn't sell well, was because it didn't sell as they had hoped. Their sales prediction was 8 million copies or something, but it turned out to be 5.2 million
(according to a site I just pulled up: gearnuke.com).
That's less than RE5 made too, which is another reason why they found RE6's sales to be mediocre.
