In a day deluged with news-Nintendy, it's interesting to read
Shacknews' report that members of Retro Studios
Metroid Prime team including, "Design director Mark Pacini, art director Todd Keller, and principal technology engineer Jack Mathews were escorted off the premises last Friday".
A single source? Well, no, apparently
IGN has confirmed the departures (albeit in a quaintly-worded story). So, the 'escorted off the premises' line is always a good one to spark controversy. While it does indicate that the parting of the ways might not have been scheduled with any great precision, it doesn't indicate any wrongdoing.
It's more likely that the exiting Retro workers are off to set up their own organisation. More news as and when we get it.
