No idea what the price would be when Barcelona debuts in mid 07, but we sure can estimate the price if Barcelona were to be released today.
Fact 1: Barcelona is Quad-Core
Fact 2: Barcelona is an Opteron
Fact 3: Barcelona uses Socket F
Fact 4: Barcelona supports at least 4-way processing as demonstrated by the task manager showoff.
Fact 5: Barcelona will be the flagship of AMD's processor family.
Now let's take a look at the price for a similar dual core Opteron which satisfies Fact 2 through Fact 5.
AMD Opteron 8220 SE --- $2,149

I would hardly believe Barcelona to be priced anything lower than $2,000. AMD is clearly using Barcelona to fotify their last castle that hasn't been damaged by Core 2 --- the 4 way and up market.
