People are right to say there is little offerings at launch but they forget that it's sadly probably enough.
If we consider the 2 millions units at launch worldwide, which is a rather small number, we can probably conclude they're still rather slow manufacturing the thing (especially with reports saying it's been in production for a while).
Zelda alone will take care of most of the inital batch since people will buy switch for it, and at best some people will buy a second game because of the novelty, but considering the total price that's basically it for the first month.
Mario Kart will probably take care of the new stock the following month. There is little room for third parties considering the audience and I expect the retail games launching in the first month to sell rather badly. Low effort ports are the right way to do it for them.
Maybe if something nice comes out in early april, we'll see.
Unless they managed to stockpile, playing all their cards at launch is probably a bad idea. I'm not even surprised Bethesda chose to launch skyrim later when the device will see the most of its sales.
