Sony warns of PS4 stock shortages ahead of Christmas

Sony has warned that stock of PlayStation 4 may be difficult to come by next week as it fights to keep up with consumer demand.

"If I look at Europe I think it is potentially, for the second year running, going to be quite inventory challenged," Sony Computer Entertainment CEO Andrew House told Reuters earlier today.

"I'm not going to say you won't be able to find a PlayStation 4. I think it's going to be kind of hand to mouth in terms of that market."

House is reported to have told Reuters that Sony is doing its best to strengthen production to deal with the demand.
