Well it has been confirmed, Modern Warfare 2 will release it's downloadable content on March 30th for the Xbox and PC, 30 days later for the PS3. It has been named as the 'Stimulus Package'

The DLC will apparently contain 10 Maps, 4 of these being maps ported from Call of Duty 4 (Shipment, Vacant, Overgrown and Crash, the others are named as Abandon, DCWH-The White House, Compact, Revolt, Complex and Storm.

There was a leaked video which seemed to show testing of these new maps, they were posted on Youtube and Vimeo but quickly were removed by request of Activision, this seems to make the validity of this video ever more true.

To confirm the Cal of Duty 4 maps will be present Infinity Ward has created this website which would suggest it to be true (Mapathy)

So what are your thoughts on this? In my own opinion this is quite a shock, i thought they would release less maps than claimed, maybe around 4 or 5?, Will this push up the price to around £9.99 on the consoles though?

UPDATE: More information has been provided, On the XBLM there is a preorder page which provides details, it seems there will only be 5 maps now, here is a summary.
