User blog comment:Argorrath/Activision confirms next Call of Duty for this year/@comment-1913529-20130209074817

NO SPLITSCREEN; it cuts vision in half, the bottom player is usually noob, noobs = losing teams, losing teams = frustration. Plus, it only increases the potential for boosting. This is a problem in MW3's Infected - one blocks doorway while other kills and boosts. I've encountered five of those so far this month.
