I, like many, enjoyed Other M, and it's a good entry in the series, provided you can get past the dodgy dialogue and story...
The hate always seemed to be OTT for my liking, many people who hate on the game probably haven't played it (and I know this for a fact).
I say 1.4mil is likely, if it continues selling as it is for another year, like most Nintendo games. And Nintendo will be fine with that.
