Entirely possible it is a mistake. If it was, I would expect to hear from them soon and the specs page updated...
But, where does ASUS discern the SPs? I don't see it on the box... You have to dig down to the specs on the webpage, no?
EDIT: Yeah, also a good point, I mean, good thing we can return it when we get ripped off by AMD and its AIBs for whatever reason we are getting ripped off. (that was sarcastic, btw). The point isn't about the ability to easily return (awwwww shucks, they got me, derp), but the fact that there is misleading information out there.
Anyway, if it really was a mistake, why hasn't AMD come out and said hey, MSI/ASUS/Whomever, its a 560D... please update? These cards have been out for a few months... its not like they are new and this is the first time they are seeing it. Clearly it looks bad as is, so I really do not understand why a statement hasn't been made, at least to AIBs, and the offending misinformation updated over these lasts months.
