Sadly, I'd say the most likely answer to the question above is something along the lines of "I doubt it."
That's mainly because although the first two Denpa Ningen no RPG (aka THE "DENPA" MEN) titles have sold surprisingly well since they were first released in Japan, all signs--such as Genius Sonority CEO Manabu Yamana's comments at the beginning of this recent Q&A--point to them not selling as well elsewhere.
Given my undying love for both previous entries in this colorfully charming series of digital RPGs, I obviously hope the just-announced third one, which will hit the Japanese 3DS eShop on Aug. 7, makes its way across the pond at some point--even if the earlier ones were out-and-out bombs in my neck of the woods.
Actually, I'd feel that way even if I wasn't a "DENPA" MEN fan, thanks to all of the additions that seemingly will be included in part three. I could use a bunch of bullet points and text to explain them here, but I think a much more appealing tactic would be to ask those of you who are interested to watch the video above, which was excised from this recent Chotto Nintendo Direct broadcast.
Sadly, the most enticing aspect of Denpa Ningen no RPG 3 for yours truly is the new head shape that looks startlingly like those cartoonish piles of poo you see all the time in Japanese anime, manga and video games.
