According to Iltalehti's information, outdoor regular season game between Jokerit and HIFK is official and will be played at the Olympic Stadium
I know Jokerit owner Harkimo have tried to get this game to the Olympic Stadium before but the price was outrageous...I guess the "Stadium people" realised this will be a good culture thing for the city and dropped the price.
Edit. Both teams will have press conference today at 13:00
Edit. Confirmed, the game will be on Saturday 5th of February 2011
Which is a good thing becose without dem der sponsors SM-Liiga would be as competitive as Mestis in no time.
Actually, I think the amount of money a team get's from a jersey advert is probably fairly low. Cleaner, better looking jerseys with fewer ads would create more revenue from fan merchandise, as the current dish rags are not very appealing products to buy. Furthermore, less adverts and more coherent style would make the whole game look more professional and respectable, at least in the eyes of casual fans.
