Multiple sources have told VGC that the platform holder is planning to hold an event to coincide with this year’s anniversary, which marks 35 years since the start of the mainline Super Mario series in 1985.

As part of its anniversary celebrations, Nintendo will reveal plans to re-release most of Super Mario’s 35-year back catalogue this year, remastered for Nintendo Switch, VGC was told.

Nintendo will also release several other Mario titles in 2020, including a new instalment in the Paper Mario series.

The plans are set to be revealed alongside new details of Nintendo’s partnership with Universal, and the pair’s Super Nintendo World theme park attractions and animated Super Mario movie.

Nintendo has already unveiled one flagship licensing deal planned to commemorate the anniversary: a special interactive Lego Mario set which sees players collecting coins and defeating enemies in real-life ‘levels’.

The Super Mario 35^th Anniversary reveal was originally due to take place as a physical event at E3 in June, VGC was told, but Nintendo is now reviewing its plans in light of the ongoing COVID-19 pandemic. E3 2020 has been cancelled due to the virus outbreak and Nintendo could instead opt for a digital showcase.

Approached for comment on this story, Nintendo said it “does not comment on rumour and speculation.”

Nintendo last celebrated a milestone Mario anniversary with the series’ 30^th anniversary in 2015.

The company commemorated the occasion with various events and merchandise, including two special edition 8-bit Mario Amiibos. Super Mario was licensed for products from Hot Wheels, Moschino, Trump cards and more.

That year’s celebrations culminated with the release of Super Mario Maker for Wii U in September 2015, exactly 30 years since Super Mario Bros.’ original release for Famicom in Japan.

While its core business remains making and selling games, Nintendo has increasingly moved to leverage its popular IP in various ways in recent years.

The company’s new Nintendo Tokyo store opened in November 2019, while the Super Nintendo World theme park land at Universal Studios Japan was scheduled to launch this summer.

I will go crazy if I’m playing Mario galaxy and Mario sunshine on my switch by the end of the year

Mario 64, and 3D world yes please. Or maybe a pile of 3ds and older Mario games.
Although remove the blowing from 3D world (does switch even support that?)
Also maybe the Captain toad Treasure tracker. The slow paced "puzzle" doesn't jazz well with the constantly moving platformer. But also necessary because it was 5 green stars.

@curl-6 if this is true, will that make you a happy Switch owner?

Mario Galaxy and Mario 64 remakes/remasters for the Switch is what I've been wanting the most. Mario Odyssey (and RPG Pokemon games) are the reason I bought a Switch in the first place. 

Cool stuff. Already own all the games, but I'll likely double dip for some of these (if true).

Since we are on VGChartz, here is our article on the news.

Sources: Nintendo Plans to Release Old and New Mario Games on the Switch in 2020 for 35th Anniversary

Nintendo has big plans for the 35th anniversary of the original Super Mario Bros., according to sources who have spoken with Eurogamer and VideoGamesChronicle. The Nintendo Switch first-party lineup for the rest of 2020 will be dominated by old and new Mario games. 

The sources say that Nintendo "plans to re-release most of Super Mario’s 35-year back catalogue this year, remastered for Nintendo Switch," as well as releasing "several other Mario titles in 2020, including a new installment in the Paper Mario series."

The sources also mentioned a remaster of Super Mario Galaxy is in development, alongside other 3D Mario games and a deluxe version of Super Mario 3D World with new levels.

The plans are set to be announced alongside new details of the Super Nintendo World theme park at Universal and the upcoming animated Super Mario movie.

Nintendo had originally planned to make the announcement at E3 2020 in June, however, the expo has been cancelled due to the coronavirus (COVID-19). Nintendo is now looking into a new plan to make the announcement. 

Nintendo had last celebrated a Mario anniversary for the series' 30th anniversary in 2015 with events, two 8-bit Mario amiibos, Super Mario Hot Wheels, and more. 

Lol wut ?

Context is key. I wasn't asking for the game - I was asking for it to be removed from the Mario game.

Also combines that sentence with the previous sentence. In which I'm talking about removing stuff.

Having to grab the wii U pad to slowly move around collect the stars doesn't go well with the fast pace nature of Mario.

I really didn't like the Captain Toad segments.  Obviously some people did, and good for them.  But it's something that is too different from the main game, and kind of interrupts the flow of things.  I wouldn't mind it if it was just an optional side thing that is not needed to 100% the main game, but I hated having to do them for stars.

If the rumors are true, it would explain why Nintendo has been extra tight lipped lately.  I could see them going all out this time, much more than the 30th anniversary.  Mostly because Switch is such a popular system, while Wii U was total flop.

I'm mostly hoping that 2D Mario gets some love.  I would like a "New" Mario All Stars game: NSMB DS, NSMB Wii and NSMB 2 (3DS) all in one game.  I would love to have all 3 games with updated graphics, but more importantly I never got a chance to play the DS and 3DS games on a TV.  However, when you consider how Nintendo recently made Link's Awakening a single $60 game, I may be asking for too much content in one package.
