Even XB360 had a higher than 300% boost in Japan from one of its biggest JRPGs, so why not PS4 too? 55k is definitely possible, although a larger increase of the baseline will need more big titles that appeal to Japanese tastes. But PES 2016 being launched in September too could help a lot about this, and after September, sales should at worst have just a small drop in October before rising a lot in November and December.
Anyway, probably the biggest boost with the biggest baseline increase too will happen in Japan with PS4 Slim.
