PSP Go experiences price cut

So soon after the PSP Go was released officially, a clone has already surfaced in the form of the PXP-2000. Could this have set off the alarm bells of those people at Sony to reduce the price of the PSP Go to $200, which is a cool $50 discount? It will bring the price point down to the level of the Nintendo Wii, but does that still warrant a purchase for existing PSP-1000/2000/3000 owners or those who are interested in picking up a portable gaming console? Let your wallet decide.
