Cited first at the Little Gamers website, "pwntendo" is a term that both describes Nintendo's ability to succeed in the videogame market ( see pwn ), and remains a popular preference to the name "Wii" to describe Nintendo's next home console. Also used by Nintendo-loyalists to describe current Nintendo devices in a superior manner to other choices on the market.
I'm saving up for the Pwntendo.
What? Xbox 360 sales are plummeting? Wow, I didn't see that coming. Well, I'm going to go home and play some pwntendo now.
