Which "new NXP dual-core $2 chip" are you referring to? I skimmed through the NXP micro-controller website but could not find anything close to this.
If you came from the future to inform us that NXP lied about their chips costing $1.99 in 10K quantities in 2015, then your beef is with the NXP marketing department, not minthd.
minthd is just relaying a number he read in a news article, which in turn relayed it from a NXP press release.
