If the previous few generations are any indication, there are going to be sellouts of the PlayStation 4 and Xbox One globally. Even though it's only June, Sony's Jack Tretton is already predicting there won't be enough consoles to go around come this holiday season.

"I certainly think, given the technology that we’re offering, given the software lineup, given the price point we have, that we’ll have consumers interested in excess of what we’re able to manufacture," Tretton told Forbes in a post-E3 interview.

Sony is no stranger to not being able to meet the demands of a hungry gamer audience, but you would think by now manufacturers would push hard to get as many consoles out as possible at launch. Obviously creating a demand is part of what makes the systems so appealing to those who missed out on the first wave, but the PlayStation One launched nearly 20 years ago, and this kind of strategy is getting old.

Did you already pre-order either console? Are you worried about not getting one at launch?
