According to  Reuters,  Sony is in the final stages of competing the acquisition. Toshiba already announced plans to focus more on its memory business.

Much changed in the memory business. Micron and Intel are coming with super-fast 3D Xpoint memory and Western Digital acquired SanDisk for $16.7 billion. Toshiba wants to deal with these threats and see off fluctuations in the memory market.

Sony has a lot of success with its image sensor business and analysts think the outfit has 40 percent of total image sensor market. That is quite a number but it looks like that Toshiba only contributes two percent.

Toshiba has a lot of patents and smart technology that Sony wants and this appears to be the acquisition's goal..

Samsung is the runner up in the phone sensor image market, and Sony is doing a better job. The buyout should be officially confirmed soon and it will go into effect in April 2016.
