Speaking to Eurogamer at Atari Live in London this week, company boss former Sony studios head Phil Harrison said he thought his former firm had succeeded in its aims with Home.
The development team had "brilliantly realised their ambitions," he said, and predicted that Sony "will have a very successful platform".
Harrison also tipped his hat to NXE.
"I was quite impressed actually with some of the things that [Microsoft has] done," he said.
"[Microsoft are] just scratching the surface of what the whole industry recognises is that customisation, socialisation and community platforms are going to be just as important as the games themselves."
