The answer shouldn’t be a surprise, but somehow the performance Gamestop reported this morning managed to catch Wall Street off guard anyway.

The company’s revenue of $1.74 billion was in line with estimates, but earnings of 23 cents a share missed consensus by five cents. More worrisome is that the company had to knock down its guidance for the rest of the year and says that comparable store sales will be down between four percent and eight percent through 2009. Now Gamestop (GME) shares are trading down five percent in a flat market.

Did I mention that this shouldn’t be a surprise? Game sales, once thought to be immune to the recession, have been slumping for months. Turns out that a tough economy may indeed prompt more gamers to huddle in the basement in front of their Xboxes, but it won’t prompt them to buy new games (used ones may be a different story).

Gamestop says it’s still optimistic that coming games, like yet another Call of Duty sequel from Activision (ATVI) and yet another version of Halo from Microsoft/Bungie (MSFT), will help perk things up. But I’m interested to note that the company didn’t cite the new Beatles version of Rock Band, from Electronic Arts (ERTS) and Viacom’s (VIA) MTV as a catalyst.

By the way, for fantasists who persist in pretending that the Beatles are coming to iTunes at Apple’s (AAPL) event next month: Stop! It’s not true.

And who knows? Maybe John Chambers, Steve Ballmer and Brian Roberts will indeed say something important today and tomorrow at Quadrangle’s Foursquare conference. Chrysler’s Robert Nardelli is speaking too. He might have something newsworthy to say.

But you are unlikely to read about it.

That’s because there’s no press allowed at the private equity shop’s annual conference, which starts this afternoon at New York’s Plaza Hotel.

Or rather, there’s some press at the event. But they’ll be on stage. And they won’t be telling their readers and listeners what they saw and heard.

CNBC’s David Faber, Becky Quick and Maria Bartiromo, for instance, will be moderating panels over the next few days. So will the New York Times’ Andrew Ross Sorkin. And network TV news bigshots Katie Couric, George Stephanopoulos and Brian Williams will answer questions themselves (Portfolio’s Matt Cooper will be moderating that one).

Am I crabby because I asked (nicely) and couldn’t get in myself? Nah. It’s Quadrangle’s event, and they can run it any way they want. But it does look like a pretty good gathering of worthies. Maybe I’ll park myself in the Plaza’s lobby and see if I can bump into some of them.
