News have been heard that Foxconn, a Chinese manufacturing plant, has been outsourcing labours in order to meet the demand they have from Apple for the MacBook Pro 2012 edition. It seems that Apple is set to release the new model before the month of July.

Updates even say that all available labours have been tapped in order to work for the development. This is because there was only 12.79 million in demand last 2011 but for this year, the demand for MacBook Pro units grew to 16.24-19.2 million.
Apparently, for the MacBook Pro 2012, Apple plans to get rid of the optical drive from the new model (in order to make it thinner) and build it with an entirely new set of components compared to the current model in the market.
The device will also have the all too famous 3rd Generation Intel Core processor ( Ivy Bridge) which is rumoured to be caused because of Apple eyeing the model for gaming purposes. With this, a high definition display should also be expected. It will probably not cost more than the models that are already out in the market today but it would surely be packed with better and more efficient hardware and software.
