Short answer: no, not at all.
Long answer:
Like it or not it even helped the Vita. With most bundles the game was pretty much an added bonus, and I doubt that many core gamers who wanted a Vita bought it for CoD:BO:D. Who got it with the bundle or who bought it without reading the reviews (meaning the small percentage of casual gamers) got a decent enough multiplayer shooter, and a Vita, that has tons of free and exciting stuff on the online store, and Im certain that most buyers will give a second CoD on the Vita another chance if it will happen (and judging by the OK sales it might actually happen).
CoD was never the Vita's savior in the west.A decent stream of quality games and a good pricepoint is. Whoever thinks that a shooter franchise will make or break a handheld belongs in the loonie house. I would argue that even tough it had lower sales AC3:L pushed more Vitas than CoD.
One terrible game will not seal a systems fate nor will it bring it to glory, and its actually a shame that many posters, who are on this site for years now, still haven't learned this.
