WallStreet Journal reports that Sony Corp. is on its way to finish off the deal with Telefon AB L.M. Ericsson, which would make Sony the sole and primary shareholder of the Sony Ericsson joint venture.
Created back in 2001, the Sony Ericsson 50-50 joint venture is one of the world's leading mobile phone manufacturers (the 6th, actually) and has attracted many brand-loyal users through the years.
Sony's goal with this move is supposedly consolidating the R&D and manufacturing of mobile devices such as mobile phones, tablets, portable gaming consoles and personal computers to save on the costs and to improve their concurrent development.
The WSJ source is cited just as "people familiar with the matter" and we've seen both highly accurate predictions from WSJ, as well as complete flops, so we'll take this with a pinch of salt for now.
