There is plenty of anticipation for a QE upgrade from the BoJ, but it sounds more like hope from speculators rather than concise analysis as to why more stimulus would generate long-elusive economic objectives. Without more stimulus, we may find the Yen crosses start to retreat in earnest. Without the BoJ's QQE program (Apr 4, 2013) and its subsequent upgrade (Oct 31, 2014), USDJPY and other Yen crosses may have been much lower than current price.
