Yeah, Kari's beauty went far beyond the physical when you factor in her personality, her intelligence, and various skills. (Though her being a vegetarian who reacts, pretty dramatically, to meat and meat products gets her a point two off.

.) Just a real shame to see her go, Tory and Grant I can cope with but Kari is much, much harder. Because she *has* been there from the very beginning and she brought so much to the show in so many ways.
Be really interesting to see if anything is coming forward as far as her and the others getting their own spin-off series. Mythbusters: Miami!
So, I wonder if this move has been part of the plan for a while now or if it was a sudden decision they didn't have time to plan for? Because if it's something they knew was coming it's a real shame that they didn't do one last "big myth" requiring the A-Team and B-Team to work together. I think the send-off of the trio deserved more than a little snippet at the end of the show.
And is this it for Mythbusters for the rest of the year? Usually they have another block of episodes in the late fall/winter.
It will be interesting to see what happens from here on an Adam and Jamie show, any other members at M5 helping out I hope aren't given any status beyond background help. Because it'd be, as Christopher said above, foolish to introduce "new cast members" to fit the roles (like the "Geek Babe") without really fitting in, earning it or really even showing it. (Again, as Christopher said, hiring a female cast-member for looks alone rather than her abilities and screen personality which Kari certainly had loads of.)
Going forward it really needs to be Jamie and Adam alone if we're going to dispense with the Jr. Mythbusters. And I do hope maybe they get more back into more complex myths and more detail when it comes to showing the planning and building.
Be interesting to see.
On the myths in this episode:
I think the "WILMA" method could still work in the case with parents traveling with children, just make an exception for those cases. If a member of the party is an adult with a child (or a child with an adult) let them board as a group. They'll still be in adjacent seats and it should still some-what stream line things.
Along another line, why not in order to facilitate better traffic-flow why not prohibit using the lavatories during boarding? I mean you were just sitting at the gate for the last hour or so and if you're doing it right you've been at the airport for two hours. Why not do what your parents did to you before going on a trip? Go to the bathroom before getting in the car (plane, in this case.)
Similarly during boarding why not prohibit getting back out of your seat to mess with the luggage in the overhead bin and stuff? Just say, "Look, we're trying to get 200 people boarded on this plane here in a reasonable time. How about you don't clog up our 18-wide aisle by messing around with your bag when everyone else is trying to board or going to the bathroom when you've had the last two hours to do it?"
Just make the rules, "Get on the plane, store you bags, sit down, and stay put!"
