During a recent interview, Aaron Greenberg, Microsoft has issued some statements Maun drive 250 GB Xbox 360, explaining that it is not currently planning to distribute consoles with larger hard drives except in limited edition bundle version.

The current record of 120 Elite with more than enough are considered as standard and, therefore, match the HD from 250 to only some special bundles, such as the upcoming Limited Edition dedicated to Final Fantasy XIII or the history of Modern Warfare 2 and Forza Motorsport 3, would be a good balance of 'trade offer.

Greenberg was keen to point out however that the change of strategy is constantly being evaluated, but currently this is the choice they deem best, I remember for example the recent announcement of the marketing of only 250 gig hdd for the Japanese market.
