Conspracy theories surround the proposed new format for motherboards, BTX or Balanced Technology eXtended. It is not very popular with many people, and this article gives some of the reasons.
There are other complaints about BTX, one major one being that Intel seems to be the only one interested in pushing it, which further supports the conspiracy theory that it's just a way to deal with their extremely hot processors. One possible limitation is that BTX's layout isn't exactly very friendly to AMD's on-die memory controller; look at the picture below of a BTX motherboard and note the difficulty in running equal length traces from the CPU to the memory banks.
