3 huge companies - Nintendo, Sony, and Microsoft - are in the process of beating the crap out of each other. It isn't wise for a tiny little company like "Infinium Labs" to jump out right in the crossfire, because they're gonna go down before the other three even notice this newcomer.
Sony is not going to go bankrupt anytime soon. Neither is Microsoft. Neither is Nintendo. All three of these companies will still be there for over a hundred and possibly hundreds of years unless some sort of economic catastrophe occurs. Heck, Nintendo has already seen 3 centuries, the 19th, 20th, and now the 21st. Sony will be a hundred years old soon enough, and MS has more than enough money to buy its way into a hundred years of existence.
Infinium Labs on the other hand, has what? A little Piggy Bank with 2 million bucks of quarters inside? Some parternships it got with other big companies? Hah, that doesn't count the same as the billions upon billions these other companies have stored up.
4 consoles? Can you imagine the amount of funding you'd need to stay alive? If a company like Ford Motor Company or Wal-Mart decides to make games all of sudden, that's fine, cause they have the money. But Infinium Labs not only has to sell its console, it has to establish its company. And you can't do that in today's console market, no siree. Nintendo was already big corporation with lots of nerdy businessmen (not to mention Disney as a partner) like the Yamauchi family before they got into games. Sony was well known and established before it got into games. Microsoft was owning the PC world before it got into games.
Infinium Labs isn't going to make it.
