And Red Sox management has done some upgrades, and is committed to be at Fenway for the foreseeable future. Fenway Park and Wrigley Field are the only major league parks I know which were 100 years old and still in use, and not slated to be replaced anytime soon.

Fenway still remains viable because since the late 1990's, the ballpark has undergone a number of upgrades to keep it viable--even the areas used by the mass media have been extensively renovated.

I still think because of the problems dealing with Wrigleyville, the Cubs may be very soon announcing they've moving to a retro modern ballpark in the suburbs of Chicago. That means it'll have most of the "feel" of the current Wrigley Field but with modern amenities for everything and the ability to play night games 55 to 60 times per year.
