"Nomura says that development is proceeding as planned based on the schedule, but that they have switched to Unreal Engine 4 for "various reasons". He goes on to say that because of the engine switch they're having some rendering issues at the moment, but that Epic Games is working closely with them to resolve any issues."

 Very interesting to see a Japanese company openly embrace a more western based company's engine especially one so recently released. The power behind that engine is very enticing so it makes sense to go with that one. The one question on everyones mind is if this will push the development back at all. In my opinion there will of course be some extra time to work out the rendering problems Nomura is talking about in the interview but with such manpower behind Epic, they will be able to work through any hiccups. No notable delay will occur given that there is no timeframe of release for this highly anticipated title.
