So it looks like these are gone too. I just logged in to see if there was anything worthwhile and noticed the hourly shoot outs have disappeared, but it doesn't look like they have replaced them with anything.
pokerstars replaced the popular 100k VIP's with the shoot outs, then got rid of the weekly round 2's and then they get rid of the shoot outs (lame as they were).
Does PS have anything now that qualifies as a true freeroll?
