I just texted my buddy. He says no Heists still. Gives me great confidence in the PC game...
You're right about Witcher 1. It would crash all the time. However W2 was much improved. I dont remember any outstanding problems with it on release. I expect 3 will raise the bar even further though if there were minor ones in 2.
I'm hoping there won't be much for bugs, and I think CDPR is one of the best companies around. Open world games are so much more prone to buggyness and since this is their first really 'open world' I'm suspecting that it'll be buggier than 2 was. But CDPR does put a lot of effort into their product and since they delayed it already, hopefully their QC dept is on top of things.
