EA are working on a secret "unannounced" project for Project Natal.
That is according to the CV of a former intern at the developer, Ross Danielson. Danielson had been working on the project since May until August as a Software Engineer Intern, doing research and development.
This is what it says on his LinkedIn:
"Software Engineer Intern
(Public Company; ERTS; Computer Games industry)
May 2009 — August 2009
Research and development for unannounced Microsoft Natal product."
Interesting. Thanks, sa.
