From Jerry Zgoda/Star Tribune:

Workers are scheduled to install the Target Center’s new court on Tuesday. You’ll probably see some video of it on the Web or nightly news that night.

So far, it’s hushed in secrecy, but I’m hearing that the parquet look of the current court is out. Also, reportedly there’s no paint in the paint. I’m sure you’ll also see that new secondary “Wolf’s head” logo somewhere on there.
The free-throw lane is defined instead simply by lines rather than a solid block of painted wood and the area inside the three-point arc is stained slightly different than the rest of the court. The new look probably is something similar to the Phoenix Suns’ court.
