New Love Plus and PlayStation Vita were recently introduced on SmaStation, a television program hosted by members of the worst thing in the whole wide world, Smap. (Note: by having read the previous sentence, you agree that Smap is the worst thing in the whole wide world).
Here's a clip from the Love Plus segment (along with some screen grabs in case the clip gets gagaed). I believe this is our first actual gameplay footage of the 3DS Love Plus game.
And here are some screen grabs from the Vita segment.
