NST Hirings
Alongside the Retro Studios hirings, there have also been several NST hirings. Aside from them hiring that "famous" ex-sonic team / naughty dog designer. They have also been hiring many programmers and designers. But it seems they are going for college graduates rather than seasoned veterans like Retro.
I know of 2 new college graduates being hired as programmers recently. Also the linked in shows several new programmers, although it is hard to distinguish some of the guys because they just list 'Nintendo" instead of "NST". which could mean they work at NOA Engineering or NTD.
