I could have told you it was coming 2 years ago. If I was the only one I should get into the psychic business.

And what about GTAV?

The stores confirmed shortages like a week ago LOL (which was before Sony said anything)

Eh...it may explain the somewhat severe drop, but I sincerely doubt that it's bad enough to mean sales won't drop further from here. Seems like stores still have the system available in some capacity anyway. I'd like to be wrong, but it's looking like 12-15k a week from here.

Sony should bring Vitas from western shelves back to Japan lol

When are those arrogant Nintendo's going to come out and apologize for the WiiU, too?
They could learn a thing or 2 about being humble and respect their customers.

oh lol

Media Create's weekly analysis has now mentioned the ongoing Vita stock shortages for Red, Blue, and White models, affecting sales. Even the more available default Black model is seeing stock declining.

So now there's even third party confirmation from an analysis firm. Doubters have anything left to say?

Putting the text of the analysis here because it will be replaced on their website next week:
ソフトの総販売本数は48.2万本、前週比74.42％。ハードの総販売台数は9.4万台、前週比79.30％。2週連続して新作タイトルに乏しかった こともあり、ソフト・ハード市場ともに年初来最低の水準となっている。PS Vita本体は発売から70週（価格改定から7週）が経ち、累計販売台数が150万台を突破。前週比は73.01％と減少しているが、これは「コズミッ ク・レッド」、「サファイア・ブルー」及び「クリスタル・ホワイト」（全て前週から半減）の在庫不足による影響である。ちなみに、「クリスタル・ブラック 3G/Wi-Fiモデル」が前週実績から1割減に留まっていることからも裏付けられる。弊社のハード購入者調査（2012年12月31日～2013年3月 31日）によると、Vita本体購入者の年齢構成比は2012年12月30日までと比較して、高校生～大学生の伸びが非常に大きい。例年、同期間は学生の 購入者が増加する傾向にあるが、前年と比較しても今年の伸びはとりわけ大きく、価格改定の実施や有力タイトルの発売によって学生層を取り込んでいることが 見てとれる。
新作では『カードファイト!! ヴァンガード ライド トゥ ビクトリー!!』が4.5万本を販売し、2位にランクイン。消化率は59.93％。同じく既存TCGシリーズを題材としたPSP『遊戯王ファイブディーズ タッグフォース6』（2011年9月発売）の初週販売本数6.4万本には及ばないものの、DS『バトルスピリッツ デジタルスターター』（2010年8月発売）の同1.5万本を超えるスタートを切っており、健闘しているといえる。

the SOC they use in the PSVita is not a TEGRA3, ITS A ibm+toshiba+sony Quad core ARM cortex A9 the GPU you listed is correct though but you forgot the + at the end. and they never was going to go with Nvidia for the PSVita's chip. it was alway's a STI designed developed Arm Cortex A9.

the Malli was not slower the ver they needed was most likely not ready to go to production the sgx was.

The shortages are affecint the sales for sure.

I noticed earlier today that the Red & Blue Vita's were in the top 10 bestselling products in videogames on amazon.jp. They've gone up and down during the day, but as of the time of writing this the Red Vita is #09 and the Blue Vita is #12.

It's not too often you get hardware in the bestseller list unless it's a LE bundle (at least since I've been checking the site) so I'd hazard a guess that this is a sign that amazon got new stock and there's an early surge of popularity for it. We'll have to see how much that translates into real-world sales on Wednesday, but hopefully it provides somewhat of a boost.
