The XBox 360 will be released in 2 "Packages":
Normal, and something in the likes of "Premium". The normal one will just contain the XBox 360 and I think some small accesoire. It will cost €299,-.
The premium package will cost €100 more (€399,-), but it will also contain an external hard disk iirc, headphones, and loads of other useful and non-useful stuff ^_^
What package are you gonna buy? I am thinking of getting Premium.
Edit: Yes I know this is in the sticky (the 2 packages), but this is more like "Which one are you gonna buy?". I forgot to add a poll, argh... Can a mod add a poll? >_>
