Third party support
Nintendo's always been about creating a system for its own needs first. But regardless, companies still follow Nintendo's lead, and in the case of the Nintendo DS, there have been several dozen who've announced interest in making games for the system. The issue is, of course, that the system is new to the scene. In an untested market. Developers are currently having a tough time anticipating their development since not only do they have to create new and unique elements for the Nintendo DS' new display and controls, but they also have to factor in budgets since it's currently unclear where Nintendo will price its games.
The PlayStation's appeal has always been its third-party support, and with the upcoming PlayStation Portable, Sony has brought on board a lot of big name companies really quickly. The appeal is the promise of quicker development time due to the power of the system -- developers already familiar with the PlayStation 2 platform can more easily move development tools and engines to the portable system. And since the controls of the system aren't much of a change from the PS2 system (minus 2 shoulder buttons and a second analog stick), tweaking control for the PSP versions of existing games isn't a big deal either.
Craig: PSP. More companies are comfortable jumping onto the PSP because it's not such a drastically different portable system.
Nix: PSP.Nintendo is the big guy on Nintendo's systems, and that's left a lot of third parties out in the cold. Sony gave them a warm home on PS and PS2, and they look to be doing the same on PSP.
Jeremy: PSP. This is a question? Sony has the biggest third party lineup in the world and with a strong commitment already by companies like EA and Activision, it's gonna be tough.
Hilary: PSP. Sony brings the third party like no one else. Nintendo's strength will remain it's first-party titles, but having full support from EA and Konami is going to do wonders for the PSP.
David: PSP. This is an easy one. Nintendo continues to alienate itself in terms of 3rd party games. This suits some people just fine, but not me.

Basicamente dicen que:
A la larga las thirds estaran mas conformes con PSP y terminaran desarrollando mas para PSP, que por ahora solo la ventaja de Nintendo es temporal dado que dieron mejores explicaciones del hardware y por eso le pudieron desarrollar mas rapido juegos.
Pero cuando se sepa bien cuales son las caracteristicas de PSP las thirds correran a PSP dado que con mejor hardware estaran mas conformes y ademas el desarrollo para PSP es muy similar al desarrollo para PS2 (tanto en hardware como en control) lo que hara que tengan mayores facilidades y menos costos de desarrollo que en DS que es un sistema complejo por tener 2 pantallas entre algunas de sus caracteristicas propias que no se encuentran en ninguna otra consola.
Ademas de que Nintendo en general se caracteriza por tener mas de sus propios titulos y mal trato con las Thirds mientras que Sony sabe como llevar mejor a las thirds a desarrollarle para ella.
En defintiva, que DS solo va a ganar en catalogo el primer año, luego Sony se llevara a las thirds de su lado.
