• Luigi Zunino didn't come through. Three months after it was reported that the Italian exec was having difficulty closing on the three-unit spread at the Plaza he put a $9 million deposit on last year, the 10,026-square-foot apartment is now back on the market. It's currently listed for $39 million. [NYO, Stribling]
• Retired Pfizer exec Gary Jortner and his wife Cindy, have picked up a new apartment at 15 CPW, just a few floors up from the smaller apartment they listed for $3.195 million earlier this month. The couple paid $5.9 million for developer Gerardo Capo's apartment on the building's 12th floor. [Cityfile]

• Michael Lemos, the son of a Greek shipping tycoon, isn't letting the dour real estate market get to his head. The London-based heir has raising the price of his full-floor apartment at 2 East 67th Street even though it's been sitting on the market for more than a year. The fifth-floor co-op, which went on the market for $34.9 million in May 2008 and was increased to $39.5 million last July, is now listed with Dolly Lenz for $45 million. [Cityfile, PDE]

• Real estate mogul and former WorldCom director Francesco Galesi still hasn't managed to find a buyer for his 16-room River House duplex, more than four years after first listing it for $50 million. The price is now down to $35 million, though, so hopefully he won't have to wait another four. [NYO, BHS]

It's been three months since we compiled a list of the 20 most expensive apartments for sale in Manhattan. So what's happened to them since then? Not surprisingly, most of them remain on the market, and several have been discounted substantially since they were first put up for sale. (Just one of the 20 sold successfully, an apartment at 176 Perry that went for 30 percent less than its initial asking price.) The grim market conditions haven't stopped several others from putting their exorbitant homes on the market. Since we put the list together, a 78th-floor penthouse at the Time Warner Center hit the market for $65 million and a $47.5 million listing at 15 CPW surfaced. But if you're interested in seeing what happened to the original 20—and get a glimpse for what's happening to the high-end real estate market as a whole—the results are below.

Yesterday we shared with you New York City's most expensive apartment rentals, just in case you haven't been killed in the market these past few weeks (or maybe you won the Powerball a few weeks ago?) and have been looking to upgrade to a fantastic apartment without making a long-term commitment. Today we've rounded up the 20 most expensive apartments for sale in the city. Pick up an overpriced co-op on Park Avenue for $30 million and you'll sleep better at night knowing you played a key role in boosting the city's ailing economy! (At the very least, you'll know you paid for a few years of private school for some lucky real estate broker.) One note: This list only includes "official" listings, which means apartments that are only rumored to be for sale (such as Richard Ullman's $75 million penthouse at 15 CPW or Courtney Sale Ross' duplex at 740 Park) aren't represented. But there's plenty of overpriced property to choose from regardless!

Page Six Magazine published a handy little charticle on some of the most powerful co-op boards in town and the board members who stand between you and that $20 million co-op.

• Loews heir Jon Tisch is rumored to be paying $48 million for an apartment at 2 East 67th Street, the co-op that's also home to Leonard and Evelyn Lauder and Arthur Carter. Tisch and second wife Lizzie have been renting at Trump Park Avenue since Jon sold his duplex at 950 Fifth Avenue to Starbucks CEO Howard Schultz back in January. [NYDN]
