I forgot about the June investor's vote, which has this quote making more sense:
(From the Financial Report Q&A) The titles we are preparing to show you at E3 vary from being nearly complete to still in the early phases of development but with the core of its appeal noticeable. Therefore, our strategy of focusing on software has not changed.
Nintendo as of recently focused on titles that were close to being finished on a developmental scale. Especially with Wii and DS, titles were revealed close to their release dates (within 6 months). This has waned a bit with the Wii U (with games like X), and I suspect that that's because Nintendo is trying to garner excitement and trust to both potential and current Wii U owners that games are coming out and they should be excited about their system's future.
We'll see if the system's future is bright with this year's E3. I'm sure many investors are eager to see what the future will hold.
