Usually, hearing anything about leaked information from a major retailer comes with a list of caveats—the source may be old, dates could be placeholders, or it’s all an elaborate Photoshop troll job from some Internet fiend. But this latest rumor has some definite legs thanks to some solid, concrete evidence from a pretty clear insider snapshot of GameStop documents.

That anonymous source tipped off Zelda Informer about the Wii U’s full launch line-up, with a picture of the full list.

Looking at the photograph closely, it definitely looks like an official mass-produced document from a professional source, listing 30 different Wii U titles, all with updated information about when they’ll launch.

Frustratingly, there’s no actual release date appended to any of these games, but here’s the full list:

2K Sports

• NBA 2K13 – Holiday

D3 Publisher

• Ben 10: Omniverse – Holiday
• Family Party: 30 Great Games (Working Title) – Holiday
• Rise of the Guardians: The Video Game – Holiday

Electronic Arts

• Mass Effect 3 – Holiday

Maximum Games

• Jett Tailfin – TBA

Namco Bandai Games

• Tank! Tank! Tank! – Holiday
• Tekken Tag Tournament 2 (Working Title) – Holiday

Nintendo

• LEGO City: Undercover – Holiday
• New Super Mario Bros. U – Holiday
• Ninja Gaiden 3: Razor’s Edge – Holiday
• Nintendo Land – Holiday
• SiNG (Working Title) – Holiday
• Wii U Panorama View (Working Title) – Holiday
• Game & Wario (Working Title) – Launch Window
• Pikmin 3 – Launch Window
• Project P-100 (Working Title) – Launch Window
• Wii Fit U – Launch Window

Sega

• Aliens: Colonial Marines – TBA

THQ

• Darksiders II – Holiday

Ubisoft

• Assassin’s Creed III – Holiday
• Just Dance 4 – Holiday
• Marvel Avengers: Battle for Earth – TBA
• Rabbids Land – Holiday
• Sports Connection – Holiday
• Your Shape: Fitness Evolved 2013 – Holiday
• ZombiU – Holiday
• Rayman Legends – TBA

Warner Bros. Interactive

• Scribblenauts Unlimited – Holiday
• Batman: Arkham City Armored Edition – Holiday

Most interestingly, that leaves Sega and Maximum Games as the only developers/publishers with titles that may not be launching alongside the Nintendo Wii U this year. If the Wii U is due in stores during the same rumored months that have been discussed around the gaming industry, that leaves the bulk of the 30 games to debut in the “launch window” period that’s clearly aimed at bulking up holiday sales.

Judging by the list’s terminology, that means 22 games will be playable on Wii U right off the bat, with the following bumped to nebulous “launch window” time:

• Game & Wario (Working Title) – Launch Window
• Pikmin 3 - Launch Window
• Project P-100 (Working Title) – Launch Window
• Wii Fit U - Launch Window

It all looks very legitimate, and definitely gives an insight into the launch strategy of Nintendo—they’re putting everything on the table right up front. When the original Nintendo Wii launched, 21 games were ready for consumers to buy immediately.
