PSP Phone aka Zeus Z1 is not the PSP2, they just so happen to have been leaked at about the same time, the PSP2 is an entirely different system and we know very little to nothing about it. Other than that developers claim it rivals the power of early PS3 games and that it may have 2 thumbsticks instead of 1. Everythng is really speculation at this point though, so we'll see how things pan out in the next few months. Hopefully the PSP2 will be very successful.

no one knows... just like everyone had a huge surprise that the wii was a Huge success... who knows psp2 might shock the world

That's just what people on the internet do. Always speculating about something that hasn't been announded yet.

Look at "Wii HD"

I expect it to be less successful than the PSP. The original PSP launched with all the confidence of the PS2 behind it. Confidence isn't everything, but it is, to some degree, a self-fulfilling prophecy, and it was a huge benefit in the early years of the PSP. Everybody just assumed Sony would sweep the handheld market off its feet like how they waltzed into home consoles, and developers and media planned accordingly

The PSP2 won't have that confidence. All the confidence is already invested in Apple and Nintendo. Sony has to change the nature of the game, and that's never an easy feat.

I hope it will be successful, but we know it won't come near to Nintendo's popularity. They just dominate the handheld scene, and always will, until Sony creates a mascot more infamous the Mario (hint: they never will).

I could have written this myself.

Since I didn't I have to ask if you've been stalking me?!

It all depends on the price and the launch games.

If Sony can muster enough development support for this go round then I don't see it turning out too badly.  I mean if it gets almost all the same 3rd party games as the 3DS and it gets Sony's exclusives then I could see it fairing well in the marketplace(Kinda like the HD twins).  I just don't know that the developer support is there.  Only Japanese companies really still support the PSP and I don't know if they can afford to make games that are more like PS3 games as that type of expensive investment was the reason for the smaller Japanese devs to retreat to portables in the first place.

Developers are going to be more cautious... lots of teams got burned on PSP1.  Sony had a lot more goodwill and backing last time around, now they're really going to have work twice as hard going in.

Wild guess, PSP2 will sell less hardware, but more software than PSP1.  It'll be stronger than PSP1 was in western markets, but weaker in Japan.

The last option should be "Dead on arrival".
