Already mentioned it a few times in the past. Steen Pedersen is a former national (head) coach of Denmark ... 90's/early 2000's iirc. He usually does co-commentary during the Denmark Open streaming as well. http://www.badmintonengland.co.uk/show_news.asp?section=13&itemid=4403
He's the guy who started this AC shutdown rumor. He's LCW's hardcore fanboy. When I watched WC 2011, I so wanted to see his epic face right after LCW's lost. GC is a lot neutral though. Luckily, this dude didn't commentate 2012 Olympics.
So the AC was SHUT DOWN...it's a fact...they did not however mention that it was the cause of LCW's loss...it did however had an affect on the drift in the stadium...shut up about it already!
It's NOT SHUT DOWN. Go to BWF offical site and read the investigation result in the global news section. Your m'sia source is here. http://www.thestar.com.my/Sport/Badminton/2013/08/15/China-denies-aircond-switchoff.aspx
GC is good. What's the name of the other guy who commentated 2012 Olympics MS final? Steen had commentated 2011 WC MS final, he's quite good as well except his bias to LCW. I know he is a good friend with Lee, but you just can't bias every shot to LCW. I still prefer the Olympics MS final commentating combo.
2011 WC commentator was Morten Frost, self-proclaimed mentor of LCW (having a hand in bringing LCW into the Malaysia program). It is very interesting that both criticized/questioned LCW's court sense and tactics.
Somewhat off topic I think the other commentator (Richard) is calling volleyball right now for FIVB http://www.laola1.tv/en/int/volleyball/fivb-world-grand-prix/china-usa/video/201-1922-130648.html
