The other interesting thing to note is the shortening difference between the Xbox 360 and the PlayStation 3. The 360 is no slouch, sitting at around 28.5 million units worldwide. Their sales have not stopped, though they certainly have waned, which may be due to the PS3. Sony's beast has seen a growth spurt of sorts and now touts over 21 million consoles sold, narrowing the game between themselves and Microsoft to only around 7 million. A taste of things to come or merely the market filling out? This is a bit hard to predict at this point, as both Microsoft and Sony have a lot of things going for them.
Neither Sony nor Microsoft, however, can really hold a candle to Nintendo at this time. The Wii is still outselling both consoles at nearly a 2 to 1 ratio. Can that continue for very much longer? Sony's biggest hurdle, in my opinion, still remains their price. Microsoft has the cheapest console and Nintendo has the greatest sales, whereas Sony has both the highest price and the lowest sales. While it's not completely that simple, it's not a coincidence either.
