I don't think that Bulldozer will beat Sandy Bridge, will match it at best. Their flagship will probably launch at $250 and be about comparable to the 2500k...but the architecture is so radically different than anything AMD or Intel has ever done, so it's hard to compare them apples-to-apples.
I love pure fanboy speculation.
I mean nobody knows anything, so giving your hypothesis about something in the future is just....well....speculation with zero facts.
AMD is very careful not to leak anything these days because it has backfired on them in the past.
