Lots of 3DS games cancelled. A worrisome trend?

I can think of a similarly large list of PS3 games announced in 05-06 that never saw the light of day. Though I don't think it was publicly known most of them were canceled so early in the system's lifespan.

Eight Days
The Getaway 3
Ni-oh
Coded Arms: Assault
Eyedentify

etc, etc.
