From the AP, the Diamondbacks plan on installing a brand new high definition scoreboard. They say it will be the largest in all pro sports.
"The board, estimated to cost $10 million to $12 million, will be 144 feet wide and 55 feet high, and it is expected to be ready for next season's opener. It would be 900 square feet larger than the biggest existing board, at Atlanta's Turner Field."
The BOB is one of the nicest looking stadiums (I've never been there) on TV and I imagine for those who attend games next year, the new screen will be a sight to take in for sure.
