lol, it is too early to give it up. Look at what happened to the PS3, back in 2006-2007 everyone was spelling its doom and today it is a very well stabilished console. Not marketleader but easily the best console for many players.
The worst part of a console cycle is its launch, where it is most expensive, has few games, is least known.
Holidays are coming, big titles are coming for the Vita, it will do just fine. If all worst comes to worst, Sony can still drop its price.
Not all is lost. It sold 8.8k units in Japan last week, this week it sold 11K. It went up without any new releases. Compare it to the Xbox 360 who sold not even 1K and you see it's not as bad as people are saying.
