sony buildingSony on Wednesday said it planned to rearrange the senior management of its video game unit just months after hackers shut down the PlayStation Network for nearly a month.

The management reshuffle is unsurprising, as Sony has faced many issues recently along with the attack on the PlayStation Network. Not only was it slapped with lawsuit associated with the theft of personal data during the PSN attack, it also had its Sony Pictures website hacked with personal data stolen there too.

Kazuo Hirai, president of Sony’s games unit since 2006, will be replaced by Andrew House, head of the European video game unit, on Sept. 1. Hirai will continue to oversee the gaming business as the unit’s chairman and retain his post as executive deputy president of the entire Sony group.

With the upcoming launch of the PlayStation Vita portable console and the push to make the PlayStation 3 more popular, House will have plenty to do. The Vita faces stiff competition with the Nintendo 3DS, the successor to the mammoth-selling Nintendo DS.

Are you looking forward to Sony’s upcoming offerings? Do you trust them to keep your personal data safe again?
