Mass effect 3 ps3 KOA

Hi!
I was thinking will it still be able to get those Kingdoms of amalur demo items for Mass Effect 3 on PS3?

In that thread, there reads that those are still possible to get but in PSN there is no KOA demo. So is it anymore possible to get those items or will i have to get PC versions or something?
