It looks as though Sony America has lost two of its key executives: VP of marketing Scott Steinberg, and SVP of publisher relations, Rob Dyer.
According to SCEA, Scott Steinberg has resigned, but it is unclear at this time the reason for his resignation or where he will work next. A source close to IndustryGamers states he was let go and escorted out by security - but either way, it's normal for security to escort an exiting employee out of a corporate building.
Steinberg joined SCEA in 2007 after leaving his a VP position with SEGA of America. He previously worked with Eidos and Crystal Dynamics, as well as Roxio and Liquid Audio.
SCEA has also confirmed to IG that Rob Dyer has quit the firm, and it has yet to announce a replacement for him either. Dyer will join Zynga as the new head of partner publishing, although this still remains unconfirmed by Zynga.
Dyer, like Steinberg, previously held position at Eidos where he was president from 1998 to 2004, and he was also president of Crystal Dynamics from 1994 to 2000. He joined Sony in 2008.
Back in October, SCEA appointed Guy Longworth as its new senior VP of marketing and PSN,taking over for Peter Dille, who announced back in March he was leaving the firm.
