Indeed, Capcom's priority is with their own titles, and the number of people working on SNK Vs. Capcom has suffered as a result. On the other end of the coin, while SNK lacks the people to develop the game in a timely manner, they are the one's saddled with the task of promoting and hyping the game. Unlike Capcom, who's future is certain thanks to Resident Evil titles, SNK has more eggs in the SNK Vs. Unfortunately, SNK has never been very good at PR, or at least, not been very wise in choosing their PR representatives.
History is rife with the false promises and white lies of SNK press releases.
Warrior's Rage for an example of that. While lack of marketing and insufficient staff are valid reasons as to why the game has been delayed, it might interest people to know that SNK Vs. Capcom is actually complete. That's right, folks, 10027777755234perational and ready to go. At least the arcade version anyway.
