Completely agree. But it's early. 3DS had more or less the same thing happen after it's launch, and they salvaged that situation.
It's relevant to note that Nintendo seems to be trying to resolve their "bad launches" problem with their unified platform idea (however they're phrasing it). But they have to survive the WiiU and launch the next thing before we see the results of that strategy.
No, the 3DS was never as bad as the Wii-U at any point and time, in-addition it's a handheld. Comparisons are completely pointless IMO.
