This will be hard to get used to…http://www.chicagorealestatedaily.com/cgi-bin/news.pl?id=33292
They announce it a while ago, I think it will generally be called the Sears Tower for at least a generation (at least by the locals). 
Just like that minor league baseball team here still plays in Comiskey Park even though that has been renamed. 
I still call Allstate arena the Horizon and G-D only kitchen knows what the World Theater,Twitter Center etc is named this year.
Rick I also call it the Cell as it kinda fits plus the old owner really sucked from everything I read in history.
Bill Veek deserves the name more in my book.
The Willis Group’s owner told reporters that he wanted people to nick name it “Big Willy”.
Now, if I can only get them to paint it orange!!!
Please, people, start a letter writing campaign!!!
And I thought it was named for Bruce Willis 
They’re even considering painting it silver. As the years pass, it keeps getting smaller. There are three buildings now taller than it, soon to be a fourth.

and Rick… pertaining to that ‘minor league’ team, here’s some numbers you hate to hear…**2005 **!! 
It is still the tallest building in the world if you count the antenna.
Ouch 
Without checking, I thinkthe CN Tower is higher and possibly the one inDubai.
It is still the tallest in the USA
Well if they ever get done building the arn thing I think the Spire will be the tallest.
