Back on topic.
I posted this before, but it may help better explain the kind of outsourcing they were likely referring to:
"The game's exec producer Hiroyuki Kobayashi said that Capcom has around 150 people working on the game within Japan, and over 600 employees in total around the world involved in the title to some degree."

I know some people will think I'm just blindly defending DmC or Ninja Theory, but I really don't believe this statement refers to that game or how it was developed. I think the outsourcing statement probably refers more to the bit of information above. The development of games with massive teams spread out all over the world will always results in a game that lacks cohesiveness and as a result overall quality. An obvious and important lesson you think most game companies would get through their heads, but it always takes significant losses for them to understand.

The next game in any of their franchises shouldn't require pieces of the game to be developed all over the world. When they hire a developer, western, eastern, or otherwise, that should be the only and main developer, if they want to have a small number of creative consultants to oversea an outside developer like DmC did (I believe it was 10 capcom overseers) that is okay, but having 450 people around the world making pieces of a game to put together is NOT.

Also, for future games developed outside, their should be a contractual requirement for the developers hired that there be no outsourcing, because look at what Gearbox did to sega, they outsourced the aliens game to timegate, when THEY themselves were hired by SEGA to make the game. If Sega wanted TIMEGATE, I'd assume they could have just paid timegate to develop the game.
Also, the term "outsourcing" generally refers to the practice of finding "cheaper" studios to do secondary work on major titles, that's why I think it doesn't necessarily refer to DmC, because that wasn't given to Ninja Theory in order for Capcom to save money. If anything DmC was given a larger budget and likely cost more since it was a total reboot requiring the creation of new art and animation assets; the most expensive part of new game development.
However, even if the above is true,, the loss they booked due to restructuring is substantial (Around 70 million dollars), so it is possible that a lot of future games including DmC2, regardless of quality, may have been victim to an overall policy change,.which to fans like me would be pretty crappy.
