To me its not really clear if they are trying to get control of the call of duty name and or series itself or just modern warfare. The news articles are saying things like "Though no new titles were revealed, today's announcement emphasized the fact that Respawn will have full control of all intellectual properties it creates" and "Now that the team is in control of the games and brands, we can ensure that the fans are treated as well as they deserve" to me that means COD and MW but they then go on to state "the pair alleged they were promised control of the Modern Warfare brand" which sounds like they would just get MW and not the call of duty name. If Activision loses rights to the call of duty series what would result of the COD games currently being developed by Treyarch and sledgehammer and the call of duty division that Activision created . I hope they get control of everything because I am sure they will treat it more as a game and try and to what is right for the fans not as a large cash tree which is what activision is doing.

That quote is referring to all future games Respawn creates. They're currently trying to claim rights to the Modern Warfare brand (or any Call of Duty game that takes place after the Vietnam War) in the lawsuit they've filed against Activision.
 
From the looks of things, this whole dust-up with Activision seemed to be about control of the Call of Duty and Modern Warfare franchises as well as their freedom to work on something new, and not just another MW game.
 
This deal with EA where they maintain control over their IP is them making sure they don't end up in a similar situation where the publisher is telling them what they have to make and how they have to make it.

Tbh i don't care about the modern warfare name. I would love to see what these talented individuals can create next!

iirc they essentially got a veto on any Call of Duty branded game set during or after Vietnam.  Whether that was limited to their term employment remains to be seen.
 
I'm pretty sure the CoD and MW brands themselves belong to Acti, so these guys couldn't use them now whatever happens - they just might still have a say in how Acti uses them.  But 'promised' sounds like 'it isn't in a contract', so I would guess they're out of luck and Acti can use them however they want.  It was probably more of a "if you break this promise, we will leave" sorta deal, which they've done now anyway.
 
When they say "Now that the team is in control of the games and brands", they are talking about any future brands they create as Respawn - these brands will be entirely owned by Respawn, with EA merely publishing for them.
