Yeah, if it were unranked, Microsoft would be liable for false advertisement lawsuits. So, I believe they will be fully dedicated servers Now, with Sony having a huge cloud service as well. If Activision doesn't persue getting clouds servers on PS4 for this game, then I might seriously cancel my Pre-Order for this game and just get Battlefield 4. No reason to play a game that won't make an effort to support the system that I choose to play.
Honestly, it's great for XBox players, but if they don't pursue dedis for the PS fan base, it's a huge slap in the face. Many other games, including Battlefield put them in their games, why not the same for COD? Activision is too cheap?
Could be a deal breaker for me and I'm not switching to XBox, I'm content in skipping COD for not making a key feature like this equal on both platforms.
