Project Hammer has officially been "put on hold" so we can mark that one off.
And also, I don't think that Nintendo bought Monolith for the purpose of casual games, although it would be possible, perhaps, to offload more core-game projects onto them to free up more internal studios for non-core titles.
I still don't see a decline in their regular offerings myself, however.
Nobody is crazy enough to accuse me of being sane.
