I wonder what Jovita must be thinking. It has to be something along the lines of, "Alright, Miss Monica - let's speed this thing up a bit..." ;D
As for Justin, he has strong reporting chops, which will hopefully serve him well in the long run. I'm still not a fan of his behind the anchor desk. Plus, there's the whole "nepotism" thing. But he is a journalist and not just another pretty face, so that's a plus. I agree with gregg75 - I really like John Bachman and think he would have been a strong choice for the primetime gig. However, I also really think Fred Blankenship is primetime material as well. I wouldn't be surprised to see one (or both) of them eventually jump ship if offered a higher profile somewhere else. They're quite good at what they do.
I doubt this change at Channel 2 will do much to shake up the ratings. Now when Monica decides to downsize her role, that's when we'll likely see the earthquake...
