Leaked internal Microsoft documents posted to the Resetera gaming forum this week showed an Xbox roadmap from May 2022 that includes support for crypto wallets.

The massive leak was blamed on documents related to the Federal Trade Commission's lawsuit to block Microsoft's $69 billion bid for Activision Blizzard being uploaded before being redacted.

"Several documents submitted in the court proceedings related to our proposed acquisition of Activision Blizzard were unintentionally disclosed," head of Xbox at Microsoft, Phil Spencer, wrote in a memo to staff seen by The Verge. "I know this is disappointing, even if many of the documents are well over a year old and our plans have evolved."

The new "ecosystem generation," including consoles, phones, web browsers, a handheld system, PCs and a "cloud console," as well as artificial intelligence and machine learning support, is not planned for release until 2028 and may be subject to change.

"It is hard to see our team's work shared in this way because so much has changed and there's so much to be excited about right now, and in the future," Spencer posted to X (Twitter). "We will share the real plans when we are ready."

Rumors and speculation have swirled for years that the likes of Microsoft, Apple AAPL , Amazon, Google GOOG parent Alphabet and Facebook's Meta are gearing up to roll out bitcoin and crypto support.

While Wall Street giants such as BlackRock BLK and JPMorgan are tip-toeing into the world of bitcoin, ethereum and crypto, Silicon Valley companies have been spooked by Facebook's failed swing at creating its own bitcoin-inspired stablecoin.

Global regulators and central banks banded together in 2019 to quash Meta's plans for its own private, global cryptocurrency, fearing the company could rival the economic power of the Federal Reserve if it was allowed to issue currency to its more than 3 billion users worldwide.
