PlayStation Plus subscribers get first crack at the public demo starting next week on January 17 for the US and January 18 for Europe, PlayStation Blog reports. If you picked up Uncharted 3, you'll get a crack at the public beta two weeks later: January 31 in the US and February 1 in Europe. Finally, if you've got a regular ol' free PSN account, you can jump in on February 21, when the beta is open to all US users; European users get in on the following day.
