Not at all.
The "weak" launch line-up is in tune with the launch of any other system in the last 5-6 years and better than almost any launch line up before that. It lacks a heavy hitter that everyone must own out of the gate, sure, but when the thing is going to be sold out for an entire year straight (possibly two like the Wii) there's no reason not to hold off on such titles until later. Those games can also be better for it.
Also, what do you think they could have done about battery life? The current battery tech has existed since the 70s and hasn't seen much real improvment other than becoming smaller and more portable (and a bit safer, I'd imagine). The next big thing in batteries will be hydrogen, but we're not there yet and even once we are it will take many years for it to get small enough and safe enough to use in a handheld. The only gains (minor ones at that) that could have come from waiting would be shrinking the internal components, but then it would have been cheaper to just put something more powerful in instead. Do take note that it can play original DS games as long as a DS can, because as I mentioned battery technology hasn't improved in many years.
So you've got a launch line-up that isn't objectively bad, and in fact will please many people, and demand for technology that doesn't exist yet and won't for years or decades. On top of that, you haven't considered in the least what that would do to the company on other fronts. They would have to continue relying on the DS for their portable market, and that has essentially reached saturation. They'd also have to delay the realease of the Wii's successor for as long as they delayed the 3DS because it's both difficult to juggle two major launches at once and bad for consumers who then have to choose which they will actually buy. Finally, they'd have to spend a lot of time developing stuff that isn't making them money when it absolutely could be.
Really, I see no good reason to even consider the idea. If anything, they should have launched it sooner, but they wanted to get one more Christmas out of the DS in order to maximize profits (which is why it launched so soon after the major holiday).
You do not have the right to never be offended.
