No they took a lot a lot of market share from the Ds and is too well known.

The market is moving to DD, I expect the PSPgo and the PSP2 if there is one to be the only models available within 2 years from now.

Also, the PSPgo's only issue is price and storage. Sony is working on the storage issue, and will event\ually have an online storage feature as one of its premium services. So, if Sony can cut the price down of the go by $50 that will go a long way towards its success.

Also, the PSP2, that is if there really is one about to hit market, sounds like a great idea. It takes very little to upgrade a smart phone to a smart phone that is very game capable. Any Ipone processor could do the job. The PSP2 will be a great source of profit for Sony.
