I'm still playing planetside.  I keep my AH account paid up because I'm basically waiting for AH2.  
The reason I have no sympathy for the people who whined about Hitech's response to the lame complaints is because I have seen Sony's presence on their forums.  They lock every tech support issue immediately after not-answering it (to get it off the front screen), I haven't seen them fix an issue for someone yet, and they jerk everyone around incessantly.
For the past few days, I get a pop up every time I enter PS asking if I want to pre-order Core Combat, the new pay add-on that's coming out.  EVERY TIME I open it.  Also, every time I open the launchpad it does a re-scan of all my PS files.  It does this for everyone.  It's a 5 minute process.  A bug.  They released a big patch on Friday right before going home.  It's been broken all weekend, and they don't seem to care.  They haven't pulled the patch, they haven't responded to a single thread in the forums, etc.
...but like some dumb masochist girl, I keep going back.  There's something awfully satisfying about playing Mujahadeen out in the middle of nowhere and blasting unsuspecting aircraft out of the sky with my MANPAD.
