Sony reported over the weekend on Kaz Hirai's promotional step, stating that the information that Nikkei published was possibly a few weeks to early or may be a mistake. Sony has yet to offer Kaz Hirai the presidential position, and has refrained from stating if the information that Nikkei indeed is true or false. Sony really does love to hit the pause button on some things... Well hopefully Kaz Hirai does get the promotion, gambatte kudasai(good luck) !
