The official lyrics to "Go Go Mario," translated into English from Japanese:

Today, full of energy, Mario is still running, running
Go save Princess Peach! Go!
Today, full of energy, Mario runs
Today, full of energy, jumping!
Today, full of energy, searching for coins
Today, keep going, Mario!

Get a mushroom - it's Super Mario!
Get a flower - it's Fire Mario!

Goomba! Troopa! Buzzy Beetle! Beat them all!
Mario is always full of energy and strong!

[Spoken] The only one who can reverse the spell that has captured the Mushroom People is Princess Peach. But Princess Peach is hidden underground, in a far-off castle. Ah, the days of peace... if we could once more return to those days... to save Princess Peach and bring peace back to the Mushroom Kingdom, that is why Mario is on his journey today.

Today, full of energy, Mario is still running, running
Go and beat the Koopa tribe, go!
Today, full of energy, Mario runs
Today, full of energy, jumping!
Today, full of energy, searching for coins
Today, keep going, Mario!

Get a star - become invincible!
Quickly, go save Princess Peach!

Lakitu! Blooper! Cheep Cheep! Beat them all!
Mario is always full of energy and strong!

Today, full of energy, Mario is still running, running
He's made it to the castle and gets fireworks!
Lightly sidestepping the Hammer Bros.
Show the last of your power, Mario!
It's been a long journey but it's nearly at an end
You've done it, you've done it! You've defeated Bowser!

Princess Peach says "Thank you"
Mario's got a great big heart!

Mario's adventure is over for now, but
Mario's dream lives forever...

There hasn't been a new Katamari game since 2012, but the time may finally be coming! 

Bandai Namco just filed a trademark for "Touch My Katamari" as well as registered a domain for the same name. There are no details about the game yet, but don't be surprised if you hear of a new Katamari some time in the near future.

If you've played an Elder Scrolls game, you're probably familiar with the glowing Nirnroot plant, valued for its healing properties. If you're also playing Fallout 4 (who am I kidding, of course you are), you may have stumbled across an "experimental plant" that looks an awful lot like Nirnroot aboard an airship research station. 

I know what you're thinking, "it's just a reused asset," but, consider the notes from the scribe who discovered the plant in the Fallout universe: according to him, the plant emits a light that is a result of bioluminescence, not radiation, and makes him feel stronger when he drinks a tea made from the plant. Could they be the same plant?

It may very well be that these are totally different, but it's fun to speculate about a connection between these two universes.

Just Cause held a fan competition to create the game's launch trailer, and CoolTwinSkittles' rap trailer won. Just Cause 3 launches December 1, 2015.

This game would have launched at the same time as the film with more characters and a different story. It would have been a first person game with a lot of cooperative game play. The publisher had to shut down the companies that were working on the game due to financial reasons. 

You may have heard news of a new BioShock game coming out as early as holiday 2016, but you might want to take that with a grain of salt. These claims are based on a quote from Take-Two CEO Strauss Zelnick that doesn't exactly say what folks are claiming it does: 

The franchise is in the hands of 2K. They'll make announcements in due time about any upcoming releases. But BioShock is unquestionably a permanent franchise for our company and one that we do believe in.

Stewardship of the BioShock series went to 2K (whose parent company is Take-Two) after BioShock creator Ken Levine's development company, Irrational Games, shut down, but they've been pretty quiet about it since. The most promising peep we've heard about it comes from a quote Zelnick gave about the series last year:

We think it's important [and] certainly something that we're focused on; something 2K Marin will be responsible for shepherding going forward.... I think there's a lot of upside in that franchise. t hasn't necessarily been realized yet. And the question for the future, assuming we decide to answer the question, would be 'How do you stay true to that creatively?'; 'How do you do something exciting?'; and 'How do you do expand the market?'

So, long story short, no new BioShock game has actually been announced (yet), but 2K hasn't forgotten about it, and may or may not be working on the next game in the series.
