Really depends on the performance levels of Bulldozer. If they're competitively priced, yet underpowered as always, Intel won't have reason to be more aggressive with pricing, as they will still have market control for anything above middle grade speed .
Honestly, at this point, with all the hype surrounding it, Bulldozer is going to have to be able to warp the fabrics of space and time to not disappoint people with it's performance. Pity too, because Intel is prepping for the 22nm die releases Q1 next year, which Bulldozer cannot possibly hope to match.
TL: DR- I doubt Bulldozer will pose enough of a threat to force Intel to lower pricing
