Let's say zenimax was to purchase the MLG, blizzard and capcom. That way, they own QL, SC2, and SSF4 (plus they have a functional competition company). All of the MLG competitions then only feature those three games. Id, blizzard and capcom are redirected to improving their existing eSports titles and eventually making new, competition-worthy eSports.

I realize an eSports company will not be purchasing blizzard (or probably capcom either). But, with a couple companies that could be purchased, and can make viable eSports, I would imagine the corporate structure in question would be a highly successful business model.
