Remember the days when platform holders would first not comment on rumour and speculation regarding, for example that their console would be shrunk and key elements removed? Remember that they'd then finally have to confirm it? Back in those days it was all about video games, pwning noobs and being harrrrdcore. Back in those heady days gamers were not a cynical bunch.
Times have changed since then (about six months ago) and we are now such a cynical lot that when confronted with a voyeuristic video of a cute girl (who works in advertising) playing Wii Fit Hula-Hoop posted by a chap (who works in advertising) you don't say, "Look at that attractive young lady being filmed without her knowledge"; you say, "What a strangely alluring piece of viral marketing from Nintendo".
Cynical lot.
You're also wrong. Nintendo has been quoted (by Brand Republic) as stating that the video - posted by a Florida-based director of interactive media called Giovanny Gutierrez had "absolutely, 100% nothing to do" with it.
As for Lauren, apparently she was 'furious' when she first saw herself paraded in knickers with an invisible hula-hoop to the world. She's okay wit it now.
