Console games aren't always that frontloaded either. Persona 4G opened at 34k in NPD and went on to 350k in the West in a year. Naruto Storm 3 had an NPD opening of <150k and went on to 1 million in NA in over a year. Danganronpa opened at 13.5k and its LTD in the west is at 200k (100k in US) and was deemed a great success.
Afaik the 200k are for all Danganronpa entries, not just D1.
