Xbox Info needed

[9mm]

I heard rumor of another price drop on the Xbox due this month.
I wanted to know if the parts in the console have gotten cheaper yet? You know like they did with the ps one. Every few months or so the technology change inside and usually turned on the cheaper side or not built as good as the first bunch of systems first released.
If that price drop this month is true, does anyone know or have an idea if this unit will be made cheaper???? Ive read (back in June) on a xbox site that they will be making them cheaper and I want to get one before any kind of change over.
Or perhaps the only thing I can do is check the date on it when I purchase it. Can anyone refer a date to look for if there are part changes?
