Rumors:

Today, Microsoft revealed the price of Xbox One. It appears there will be a single SKU of the console, and it will cost $499. With Sony’s conference in mere hours, speculation is buzzing about what the company intends on doing with PlayStation 4’s pricing.

A rumor posted on Games Industry International suggests that Sony may be taking a three-pronged approach, going with three separate SKUs that will cost as little as $399 and as much as $599. It remains to be seen if this is true, of course, though the rumor states that Sony intends on clearing everything up pricing-wise this evening.

We’ll have to sit tight for just a few more hours and see if this rumor ends up being true or not. In the meantime, speculate in the comments: how much would you be willing to pay for a PlayStation 4?
I hope they don't plan on releasing a $399 model with a puny hard drive. I want to see what this $599 model is, though. That sounds like a behemoth.
