Yeah agreed for the most part. Both have great features, and it's likely the 3DS will outsell the PSP2 (I'm more interested in the latter myself). But, as you say, not selling the most hardware doesn't denote failure.
Also Xen has a point, the 3DS is launching in a few months, and the PSP2 was just announced so even attempting to compare their lineup is simply impossible as we have no idea what will actually launch with the PSP2 (and odds are Nintendo probably has a few surprises of their own in store for the few remaining months left before launch). However, the 3rd party dev support for the PSP2 is extremely robust, so at least we know both pieces of hardware are going to see wide support across the board.
