Oop. So much for the PSP Go's premium "aspirational" pricing -- several UK retailers have already discounted Sony's newest handheld to £199 ($319) after launch weekend. That's not a massive drop from the £224 ($358) MSRP, but it's still pretty notable, especially considering the PSP-3000 has an MSRP of £139 ($221). No wonder Sony thinks the Go will drive PSP-3000 purchases -- too bad it couldn't figure out a way to make the Go interesting enough to sell itself.
