To the general public it seems the DS is a better purchase in general, wether you believe that or not. The fact is a 30$ price drop won't bring the PSP to DS's price in fact it's still 40$ more expensive. 2 entier games if you buy from the 19.99$ lot which isn't tough for the DS these days a lot of the fun stuff is falling to 20$. So I doubt it'll overthrow the DS magically because it's 30$ cheaper. However a price drop could only lead to good things for sales, as it'd encourage those that may have been on the fence due to cost.
