The publisher's told gamers that it wants to resolve reported issues so that players can enjoy a "flawless" launch.
"Though many gamers have had a great experience playing the demo, we are aware that others have been experiencing server connection delays," the publisher wrote on its website.
"We've identified the root cause and have decided to close the PS3 demo in the next 24 hours to ensure all issues are resolved when the game launches next week. Our priority is to ensure that the final product is flawless at launch."
We have final Crysis 2 code in the office but are under embargo until next week so can't really comment on how it holds up. It's been pretty crazy watching the backlash to this game though. All three versions — PS3, 360 and PC — have been under heavy scrutiny for months now.
