Here's my take on the bowl situation right now.
ACC - 8 Bids
Florida St, Duke, Clemson, and winner or NC State/Wake Forest is in. Miami is essentially in. Loser of NC State/Wake Forest still has a good shot. Other than that, Virginia Tech is the only other team that would likely have a shot. If all of those teams get in, they're still one short.
Open slots: Military, maybe Independence
Big 12 - 8 slots
They'll have 8 on the dot. Nothing dramatic here.
Open slots - None.
Big East - 6 slots
Louisville, Rutgers, and Cincy are in. No one else has an easy road, but out of Temple, Pitt, and Syracuse I'd say that one of them gets hot and makes it. It probably won't be Temple as they only have 11 games and already have 5 losses. Big opportunity here, but the MAC has backup agreements with the first two available bowls - Birmingham and St. Pete.
Open slots - Beef O Brady's, BBVA Compass, maybe Pinstripe
Big Ten - 8 slots
Nebraska, Michigan, Northwestern, Wisconsin. Michigan State likely. That very well could be it given the tough schedules for the rest of the 4 and 5 win teams. I'll say one of Iowa, Minnesota, and Indiana makes it, leaving them with 6 teams.
Open slots - Little Caesars, Heart of Dallas, maybe Meineke (Houston)
CUSA - 6 slots
ECU, UCF, and Tulsa are in. Nothing else is guaranteed but 4 win teams SMU, Houston, and Marshall have shots but they'll need upsets in a few cases. One of them will get in.
Open slots - Military, maybe two more (NOLA or Beef O Brady's)
Notre Dame will take a BCS at large. Navy and BYU get into their respective bowl games. Army/CUSA leaves the Military slot open as mentioned above.
MAC - 3 slots
6 are in, with Miami (OH) having an outside shot. They have a backup agreement with Military, which leaves them with 2 extra teams. Likely to send them to Beef O Brady's and BBVA Compass unless something weird happens.
Open slots - None
Mountain West - 5 slots
Four more teams are already in, with a max of two more. New Mexico likely doesn't make it, leaving them even.
Open slots - none
PAC 12 - 7 slots
Five are in, with Washington, Arizona State, Arizona, Utah all fighting for a slot. Right now they might get an extra team in the BCS, leaving them even with a chance at an open New Mexico bowl slot.
Open slots - Maybe New Mexico
SEC - 10 slots
Seven teams are in. Mizzou, Tennessee, Vandy, Ole miss still have a shot. Vandy is likely in, while the loser of Mizzou and Tennessee is probably out. Ole Miss is the wild card. IF they make it, they cover all 10. If not, they don't. They'll likely get an extra BCS slot, leaving another game open.
Open slots - Independence, BBVA Compass
Sun Belt - 2 slots
Four teams are in. ULL is likely in. Troy is a wild card.
Open slots - none.
WAC - 1 slot
Louisiana Tech, Utah State, and San Jose State are in. That's it.
Open slots - none.
Sun Belt - 4
MAC - 3
WAC - 2
So, the following slots are what I think will be open.
Beef O Bradys
BBVA Compass (x2)
Heart of Dallas
That means we have one extra team past the 70 slots. LA Tech likely gets the Independence slot. MAC teams get Beef, BBVA, and one Military slot. That leaves BBVA, Little Caesars, Heart of Dallas, Military for 4 Sun Belt teams, and likely San Jose St (Utah St takes WAC's only bowl bid in Boise). Sun Belt snags BBVA, Little Caesars, and Military. From there, you've got one more Belt team and San Jose State battling for Heart of Dallas I think San Jose State is the team left out after Sun Belt convinces them of Cajuns' ticket sales and we all go home happy.This is just a conservative estimate. It's very possible other slots could be open and deals could be made.
Edit: I missed Boise State's loss last night. Doesn't change much except Pac 12 will likely get the extra BCS slot, leaving them full or maybe short the New Mexico bowl.
