This week's PlayStation Store Update is now live. The controversial Rock Band Nirvana track pack is here, so all you rockers out there are sure to enjoy the animated Kurt Cobain rockin' it out alive and well in this game. It's a double treat too as Nirvana drummer, Dave Grohl's own band, Foo Fighters, also shares some love in this week's release. Other big releases include Dissidia Final Fantasy for the PSP, Trine's PS3 demo and Ghostbusters: The Video Game on the PSP. Full list awaits after the jump.

Right on schedule, the US PS Store Update has now arrived. Up this week are three new LBP Dynamic Themes (PixelJunk Monsters, PAIN and High Velocity Bowling),a new QORE Episode featuring the much-awaited Uncharted 2, and loads more.

You know what comes next after the European PS Store Update, yes? That's right, it's the US PS Store Update for the week of July 2, 2009. And it's a hefty one to serve you fine too, in time for the 4th of July weekend. So in case you're feeling a little lethargic to join in on the festivities, at least you'll have something else to do to keep you busy. Among those stashed in this week's goodie bag are add-on packs for MotorStorm Pacific Rift, Cross Edge, the Capcom Classics Collection Remixed for the PSP Store and more. Full list after the jump.

Mark this day, folks, because this is the day Metal Gear Solid officially sets its virtual foot onto the PSOne Classics service. At US$ 10, it's a steal if you just wanna play it. I've seen brand new boxed copies of this game being sold for almost US$ 200. No kidding. Also included in this update are a bunch of new Rock Band and Guitar Hero World Tour tracks. I have a softer spot for the former's picks, though, since it includes Spinal Tap songs. Gotta watch that movie again. It never gets old. Crank that dial up to 11 and check out the full list of new Store items after the jump.

Much has been said about the UMD-less, sliding-screen PSP Go. Rumors and speculation will be put to the test next week during E3, but it seems a little bit of Sony's thunder was stolen by this week's biggest PSP-related headline: the alleged confirmation of the PSP Go in a suspiciously early release of Sony's own video mag, Qore. Read on for the rest of the PSP Weekend Warrior and have a look at the big news that graced these pages this week.

By now a lot of you have seen the shots of the new PSP Go in the Qore video I posted a while back. The video didn't really give us a great look at the new PSP model, however, so here are some better-looking press photos of the PSP Go. It actually doesn't seem that fugly anymore. It still looks like a black mylo though.

OK folks, it's go time. PSP Go, that is. Images of the long-rumored handheld have supposedly surfaced thanks to an early release of Qore's June issue. Not just an image, there's even a shot of the pack and a video that mentions launch games.

From teeny-weeny cyclopic warriors to lean, mean clawing machine, there's a lot of goods for you to choose from over at the PlayStation Store. We've got the update for you here right, and off the bat, I think I'd go for the free demo of X-Men Origins: Wolverine, just in case you haven't checked it out yet.

It's like Vin Diesel week on the PlayStation Store today, what with the guy starring in two of the four new game demos on the Store. It's all good, though, as I am really looking forward to Dark Athena. Things are pretty quiet on the PSP Store, though. Aside from the Resistance: Retribution demo, there's nothing really big there. Give us more PSOne Classics, at least, Sony!

Time to wake up and smell the flowers, guys! Flower is going live on the PSN this week, and boy, does it smell suhweet. But that's not the only thing to pick up from Sony's online service this week. They've also got Qore's latest episode, as well as your weekly track updates for Rock Band and Guitar Hero. Oh, oh! And the LUMINES Supernova Classic Pack is here, too!
