It's mostly articles like these that have people speculating:

That was the only one I remembered right now but I recall reading an article a few weeks ago as well about Microsoft already pushing some in-development 360 games for development on the 360's successor to establish a reputable launch line-up. Microsoft has really put themselves in this predicament though. They chose to get a headstart on the console wars by releasing a faulty console which would in a only a few years, become obsolete and sub-standard in comparison to the efficiency of Wii and PS3. Don't get me wrong, I'm a loyal Xbox 360 fan, but Microsoft made a few mistakes this time around, and they said themselves that the lifespan of the 360 will severely be reduced as a repurcussion of this. As previous posts have said, expect a new console to be announced around mid 2009.

[QUOTE="Astaroth_Slayer"]Yeah I was expecting there to be a price cut for Christmas but I really want to have a 360 for the Halo 3 release, so should I just go for a premium instead?bxgt
