I only keep hearing educated guesses, but being that Robin was unwilling to budge on the NYC move (I'm sure her husband's Atlanta business is one main reason), I guess the network decided to give in, back her and give her what looks like Brooke Baldwin's old studio. Since she's the main star of the network, you might as well present her with all the bells and whistles. They've been using their old studio since about 2006, so they were due for an upgrade anyway.
My initial reactions are good. It's wide open, Robin has a little glass desk which is good for leg peeks, the new text-like graphics package isn't intrusive, and the shot behind Robin looking at Bob's weather wall look like it has some good back leg cross potential. Jen looks like a barista behind that new desk of hers. Seriously, there's coffee machines right next to her!
Thank goodness Robin stuck to her guns, this new set has lots of potential.
