For those that already have an xbox 360: U$ 89.95 without a game, U$ 109.95 with a game.

New xbox bundles with natal:

Simple vesion (like arcade - without HDD): U$ 199.95

With HDD = U$ 299.95

Without Natal: U$ 239.99

I'm thinking in the realm of $99.99 as a standalone, or up to $129.99 with a game included. Both of these will not happen together, though...

$99 US dollars (bundled with Natal Sports style game)
$199 Slim + Natal No HDD
$299 Slim + Natal 250 GB HDD

$150, hopefully they announce a slim.

$149 Stand Alone
$249 With Xbox360

if it's only 79, how can it justify charging more for an wireless adaptor? Or more for 20GB storage?

I say, 150 stand alone, 299 bundle with arcade version. 399 bundle with the other version.

I say $69. It seems like the perfect price for an accessory which they want everybody to purchase. Its only $10 more than any full price game so its well within reach for all their audience. The earliest estimates on cost were based on time of flight cameras etc, however the modern Natal looks closer to $50 to make than $100 especially at the quantities which they will produce.

There's no point comparing those things to Natal, as Natal serves a different purpose

Natal is designed to sell games and 360s therefore it has to be relatively cheap; on the other hand the only point of the wireless adaptor and Hard drives are mainly to make MS money

Natal $80-99 with a game

12.50

Natal with a game = $99.99

Aracde = $149.99 (I doubt they will bundle with an Arcade)

Elite 120gig $299.99 with Natal + Game

Elite 250gig $349.99 (bundled with Natal + game + controller)

They want Natal to be like a the next gen Console, so I forsee no more "non" arcade 360s without Natal.

Keep the Arcade for people who have had RROD, banned console, accidentally dead consoles, whatever but I do not see them bundling Natal with an Arcade (since it is mostly software now, wont it need atleast something on the HDD? I dont know about this part)
