The MSU Athletic Department has released artist's conceptions of the proposed new audio and video systems to be installed in Spartan Stadium. These include a large, presumably HD video board in the south end zone that will have stats on it, and two smaller video boards in the corners of the north (river side) endzone. Also in the north end zone will be what's called a "Video Fascia," or video ribbon.
The proposed upgrades were approved in the fall by the board of trustees, and are said to cost $8mm, which will be entirely funded by the athletic department. So we should all send a huge Thank You to the Izzos & Magic Johnson, each of whom made a $1mm gift to the athletic department this fall.
Also, I couldn't find the tweet, but I remember for a fact that Greg Ianni (walk-on Anthony's dad, and Hollis's Assistant AD at MSU) tweeted over the summer about these upgrades, saying something along the lines of them being "revolutionary." Props to whomever can find that tweet.
