She shouldn't have used Gabriel in that teaser. Period. It settled things in a way that many people would be disappointed with anything but GK4.
I should be glad she will be making 3 new games but in the end the disappointment comes out on top.
I guess this is the final nail in GK's coffin. I can't for the life of me understand what is so difficult about finding out who owns the rights to the franchise and making a deal. It is beyond comprehension.
