The Sony hack has become a part and parcel of everyday news. Each day, a new set of confidential information exchanged within the confines of the company is being brought to light. According to a recent report, the alleged private mail trails between Sony executives provide some details on the upcoming Sony Xperia Z4 flagship handset.

In general, the unidentified hacker group responsible for the Sony cyber attack has published a slew of data, including that of Sony's current and future business plans. Now Gizmodo has provided some information from the allegedly leaked emails of Sony Pictures' CEO Michael Lynton. The mail trail apparently shows the concept design of the Sony Xperia Z4. Most importantly, the concept was being prepared as part of the product-placement pitch for the new James Bond movie "Spectre," according to BGR.

The detailed email states that Sony Mobile has showcased the Xperia Z4 concept designs for the upcoming movie and thereby revealed the release date of the handset. According to the same report, the upcoming flagship phones are slated for May and November 2015 release.

"Sony Electronics is now combing the production request list and will shortly tell us what they can provide. Sony Mobile has now provided us with the needed visuals of the new Z4 Phones," the email reads. "These phones are the planned phones for May/November of 2015. I'm attaching the visual for you to see," George Leon, Sony's executive VP of consumer marketing added further.

Going by the leaked Xperia Z4 concept design, Sony has made sure the handset looks futuristic. Even though it is just a concept design, if the product team has sent them for movie consideration, the upcoming device must be terrific, opines Gizmodo. Meanwhile, interested readers can check out the futuristic Xperia Z4 images from BGR.

On the other hand, RT reports that North Korea has called for an apology from the U.S. for spreading rumours about the country's culpability in Sony hack. The FBI report on the Sony hack investigation is reportedly grounded on "intentional allegation rather than scientific evidence" of the involvement of North Korea. As per the Policy Department of the National Defence Commission of the Democratic People's Republic of Korea, or DPRK, "the grounds cited by the FBI in its announcement were all based on obscure sci-tech data and a false story, and, accordingly, the announcement itself is another fabrication."
