Did Nintendo make the 3DS a success with the quick price drop and the release of some big games?
You're right though, generally you get one chance to make an impression and you want to ride off the momentum of a big launch.
They could reboot it, come out with different form factor at a lower price along with some high-profile games releases.
But the die may be cast.
So the 3DS had anemic launch, Vita is moribund and WiiU is looking that way as well.
Games industry is on a losing streak. Orbis and Durango may fare better but I wouldn't count on them necessarily selling as well as even the current gen. WiiU obviously will take much longer to reach the installed base of its predecessor, if it ever does.
Same fate may be in store for Orbis and Durango. They may both reach over 50 million but it may be a tougher slog than their predecessors, as they compete against other electronics entertainment devices, some of which are selling at rates that consoles never attained.
