If we're looking at this from the perspective of Nintendo, then acquiring Capcom should be a high priority. Yes Nintendo is losing money lately, but they have enough to continue on into the future.
Buying capcom helps more than just this Generation's Wii U, but also future generations of Nintendo consoles. Gaining all of Capcom's franchises is a major win, and that's before considering it locks rival companies out of those titles forcing consumers to buy Nintendo if they want those games.
A benefit to the here and now is also that Nintendo can purchase a fully operational company that can immediately be put to work producing games, which the Wii U needs. Ensuring you get an exclusive Capcom fighter, Resident Evil (possibly RE2 Remake), and a Megaman title in the foreseeable future is a huge boon for the Wii U, regardless of how poorly you feel those series have been represented lately.
The hype bomb from the thought of returning DMC/RE/VJ to Kamiya and Platinum would be amazing.
