Is this Nintendo ripping off the technology found in the existing 3rd party expansion carts?

My cart already allows movie, music and ebook playback (with a few bonus features that I'm SURE Nintendo won't be making available!!).

I was going to mention a remarkable similarity to the R4DS card also....

That works with video on the top screen and the bottom one turned off, though the article suggestion is an interesting one that i'd like to see, with controls, subtitles etc maybe available on the bottom screen.
