No. It's not. You misinterpreted Nintendo strategy.
Nintendo, much like Sega and Atari, knows that 1st party software moves systems and 3rd parties just jump on board. This has been how videogames have worked though most of it's history. This is why Nintendo also though that 3rd parties would flock to the Wii, because there was never a point were these wasn't true (save for the NES's early days). With this in mind, Nintendo doesn't need to redefine their strategy around third parties. Nintendo pushed the software, and, so far, Nintendo has proven that 1st party software is what counts. You are trying to apply Sony and Microsoft's strategies (which don't work to well) to Nintendo. Nintendo relies on 1st party software.
Also, the 3DS has a much bigger goal, one no one will expect. The industry has played well into Nintendo's hand. They have misidentified Nintendo has a "company about growing the market for grandma." This allows Nintendo to attacking and no one will see it coming. If you don't beleive me, watch the unveiling of the 3DS. Notice what Reggie talks about a lot, A problem with 3D. Then, listen to the begining of Sony's conference.
