Can good games really fix the PSP?

An interesting article i just checked out from kotaku, http://www.kotaku.com/gaming/psp/can-good-games-fix-the-psp-197728.php .

Lets take this back a couple of years, Sony and the rest of the world were in awe of the PSP, it looked slick, it looked powerful, it looked pure amazing. Nintendo fanboys (and me) were gobsmacked, no way can a portable handheld produce so much power and amazingness in such a tiny portable device and thusly creating a massive shock in the handheld gaming market... and Nintendo of course.

Now its 2 years on and now look at it, people who have got the PSP either loved it because of the in-ghetto style and look that it creates, or they hated it because it failed to produce the goods they expected. One of its main failings is the amount of AAA-quality games on the PSP.. its stupid of me to say that it doesn't have any good games because everyone knows it has those games. GTA:LCS, Wipeout, Tekken, Ghost Recon etc.. these are considered great games on the PSP purely because its like a step-son of the (more superior) PS2 versions, its certainly great on a handheld but certainly nothing to be excited about for general gamers. Then there are games like Valkyrie Profile, Tales of Eternia, Breath of Fire, Tomb Raider etc, good games im sure,i mean good PORTS im sure. Sorry, if i wanted ports i get it on the likely superior console version. Then theres the handheld exclusives, Loco roco, Mercury, Lumines, they seem to be the only decent games on the PSP, mainly because its a) Not a port, b) not trying to be a copycat of a PS2 version. But still, these games have really failed to impress in terms of sales or hype power.

Are games really the answer for the PSP though? Its UMD movie sector is pretty much neglected by major DVD/movie production studios (think of it like Sony's betamax, much hyped but much died), its mp3 ability is largely a poor replacement for a much more dedicated mp3 player (iPod, creative zen, whatever). Its other features can't justify the huge asking price for the PSP.

So what is the answer? Follow Nintendo's suit and go for a re-design (thus hurting Sony fanboys again)? or carry on with current PSP standards and hope for a new designed IP to draw consumers (i.e. Pokemon for GBA) ? Sony themselves are in danger of falling for the trap of being ignorant and arrogant, their brand name can only hold sales for so long before word goes through that their products aren't actually any good.
Of the 2 solutions i stated, one is a short term answer, the other long term, how Sony wants to play with their PSP is their decision, but the way things are going, the current games can't help the PSP and it seems more than likely that the DS lite is more than likely the winner of this mostly interesting war.
