I say pull it until Summer 2015. Retool it into something akin to Plants Vs. Zombies: Garden Warfare, or BF1943. Sell the MP for $30-$40. Sell the SP as DL only for $20-$25. Sell the battlepacks and customizations. Give some maps and modes away, sell some. It would be the perfect Summer game. You'd probably sell a lot more, and it would help overcome the hestitation of people who still feel burned by BF4. Otherwise it's very likely you're gonna get creamed by everything else coming out, and this will be the lowest-selling BF ever made.
Also, lighten it the fuck up a little. Make it a bit wackier.
