While I also enjoy the muddy, freezing battles of yesteryear...remeber, this is all about the money. And in spite of the purists who love the game for all the manly reasons...point scoring is what brings in the viewership. And more ponts are scored on an indoor field.

What it may affect is how many visitors flock to the city where it is held; otoh many of the cold weather locations attract tourists all year round (NY, Boston, Philly, DC) so I don't see it as a major issue either.
What I do see as a potential problem for those cities is a blizzard Wed-Fri blizzard right before the game. Teams will already be there but it will impact everything else.
