User blog comment:Crazy sam10/Infinity Ward explains leaving Modern Warfare series/@comment-1719617-20130601164622/@comment-71.228.88.214-20130601180020

Not to rain on your parade but...

1. different universe

2. The UK has closer ties to the US than most of the EU.

Although it would be interesting to see a protagonist return as a villain.

If we see any Modern Warfare characters they will probably just be easter eggs. :/
