Hmm, I am also waiting to see how the Phenom II x6 fares (considering I have been waiting for affordable octa cores), but I don't agree with what you said.
If you are saying that Intel will reduce prices just because Thurban has 6 Cores, then sorry It doesn't work that way. There are not many dependable reviews out till now, but from one of the review links posted in the other Thurban thread, the reviewer indicates that X6 1055T has roughly comparable performance to Core i7 860 in cinebench. If thats a sane indication of X6 performance, then I would say that these processors are just catching up to the lower range Core i7's with those two extra cores just like Phenom II X4's caught up to C2Q's with extra clocks.
If a quad core i7 has comparable or better performance than X6 at the same clock and similar price point, then why would Intel want to reduce prices. Intel may still reduce prices to eat into AMD's market, but they would not reduce prices for technical reasons unless X6 proves to be considerably more powerful for the same price point.
Other than that the main advantage AMD has on its side is relatively cheaper high end motherboards.
people should just buy whats better than than arguing in favor of what they like.
