MGM Mirage will suspend work on new casinos in Las Vegas and Atlantic City due to the dismal credit climate, the Wall Street Journal reports. The firm reported a 67% drop in third-quarter net income as the slumping economy quells consumers’ desire to gamble or spend at casino restaurants and luxury shops. Fitch downgraded MGM Mirage’s credit rating to “junk” level last week. (More MGM Mirage stories.)
