The Next Web’s Robin Wauters reported today that a deal between Facebook and Opera could be underway. If the rumor mill is correct, it could spell out a huge acquisition for Facebook. Since their IPO debacle, it has been rumored that Facebook is both a Ponzi Scheme and an overvalued social media company with no real revenue besides advertising.

If these rumors are true and Facebook buys Opera it could set up an interesting browser war between Google, Microsoft, Mozilla and most recently Yahoo!. Facebook has been trying to figure out a strategy that will focus on bringing revenue to their mobile site since over 50 percent of users access Facebook with their mobile device.

As of March 2012 there were 168.8 million Opera Mini users that viewed over 117 billion pages. Opera also recently bought two mobile advertising companies.
