I'm not 100% sure on copyright due to being subsidiary companies and such. But I think IW still hold some trademarks and stuff over the MW name, so I'm not sure if Sledge could make a MW game under their name alone. But I'm not 100% sure really, so I wouldn't put much water in that bucket. But I think the mention of a new era is sort of the give-away they're making something of their own.
