it wouldnt be that simple, especially if they have characters and anything else associated with the MW franchise. If Respawn wins the rights to the MW name and MW 3, that would mean IW/Sledge/Raven would have to pretty much scrap it all. That would include
any names, any story information, any settings, characters, MP information, etc. that has to do with MW 3. They woyuldnt just be able to change the name.
You just have to look at the facts, and realize, if Respawn acquires the rights to the MW name, anything and everything involved with MW 3 now, would in essence get scrapped. There would be no time to rewrite a new story, hire voice actors again, change
the setting, character models, names, maps, anything within MP, and have it shipped by Nov 8.
