Vita software dominates UK chart
Ten titles enter top 40
Uncharted: Golden Abyss and FIFA Football were the big winners - at #1 and #2 respectively.
The two titles accounted for an impressive 50 percent of the total sales units for the Vita in its debut week.
Chart-Track also revealed that the Wi-Fi version sold 79 per cent of the Vita's hardware sales, but declined to reveal sales numbers.
That task will fall to Sony Computer Entertainment's UK office, and an announcement is expected imminently.
Likewise, Sony has told us it will be releasing the handheld's digital download stats "in the coming days", with Chart-Track's rankings not taking PlayStation Store sales into account.
Elsewhere in the Individual Formats listings, other star performances include WipEout 2048 (#4), Rayman Origins (#6), Ridge Racer (#19), Virtua Tennis (#25), and Everybody's Golf (#26), while Ultimate Marvel vs. Capcom (#31), Little Deviants (#33), and F1 2011 (#.40) also proved popular.
However, there were many notable high profile casualties among the weighty 23 title launch line-up, including Tecmo Koei's Ninja Gaiden Sigma Plus, Dynasty Warriors Next, Ubisoft's Lumines, Namco Bandai's Touch My Katamari, Sony's ModNation Racers, and Square Enix's Army Corps Of Hell.
3DS software sales, meanwhile, remained largely unaffected during the Vita onslaught, with three Mario stalwarts standing firm in the Top 40, headed up by Super Mario 3D Land (#13), Mario & Sonic at the London 2012 Olympic Games (#24), and Mario Kart 7 (#30).
How the PS Vita fared against the 3DS (and indeed the original PSP) in terms of launch week hardware sales is expected to be officially revealed later this week.
