Rumor has it

G.T. has just been hired by the Bellagio and immediately put his plan into action

There will be a a new rack of $5 chips issued almost immediately.
420 different chips in all.
Each one will be a copy of the fine art that is being displayed at the hotel.
The reason they couldn't get the chips for the grand opening was it was difficult to get the original artists to sign the release forms.

Mr Wynn used all is connection to pull this one off
