Rumor: Xbox 540 (360 slim) in 2009?

In a follow up to the news that the 360's internal hardware will be changed to the "Jasper" setup, there is now the news that the "Valhalla" update mentioned in that story is more than just a CPU and GPU on the same chip. TG Daily thinks that the Valhalla chip will be the heart of a complete hardware revision in Fall 2009, ala the slimline PS2. While that would seem the logical course of action, all that we know for sure is that the Valhalla chip will indeed be used in the "mid-cycle refresh" of the hardware, and that it is in fact an "all-in-one" chip. Whether or not Microsoft will actually change the outer shell or not is unknown, and the Valhalla hardware update could come and go without changing the outer look of the console at all.
