Do you think the game would die without the PC playerbase?

[DPZ2]

The majority of the playerbase is PC. Game would not die, but content would slow to crawl and the game's population would stagnant and fall off at a much higher rate. Game would take less of a hit if they ceased console support.

Question. What evidence, other than anecdotal, do you rely upon for the assertion that the majority of the player base is PC ?
