The Kinect device itself will retail at Sterling 129.99/Euro 149.99/Dollars 149.99 and will come with Kinect Adventures bundled in with it.
A new 'Arcade' version of the Xbox 360 slim, which has everything but the 250GB hard drive and only 4GB of internal flash memory can also be bought with Kinect and Kinect Adventures for Sterling 249.99/ Euro 299.99/Dollars 299.99.
You can also just buy the 4GB slim on its own for Sterling 149.99/Euro 199.99/Dollars 199.99.
All Kinect games coming from Microsoft have been given a suggested retail price of Sterling 39.99/Euro 49.99/Dollars 49.99, although they have let third party publishers set their own price.
Interesting price points, to say the least. Personally, I can't help but think that £130 just for the Kinect device itself, even with a free game, is a tad expensive. It's typical though, as the thousands of people who have just bought the new 250 GB slim have no choice now but to pick it up on its own anyway.
Saying that however, with no plans it seems* at the moment to release the smaller 250 GB harddrive on its own, buying the 4GB bundle for hardcore gamers is going to be a waste of time unless you want to faff about with external USB drives.
Not to mention the fact that there doesn't appear** to be a Kinect console bundle that involves the 250GB harddrive, so all you people out there who want the best of both worlds will have to buy them each separately unless Microsoft have further announcements in store at a later date.
* When queried, Microsoft had nothing to say on the matter.
** They also wouldn't confirm or deny the existence of such a bundle, so if I've just been a bit blind and missed it, do let me know.
