CoolTechZone claims Microsoft is going to buy out Opera: "At the moment, the deal is almost through with Microsoft and Opera planning on locations for the browser’s research and development centers throughout the world. One of such locations includes India; other locations at this time are unknown."
Opera however officially denied these claims:
"Our phones have been ringing off the hook," said a spokesman for Opera. "But it's not true. We have not been bought, and we have not received any offers. It's just a rumour, like the Google rumour last week."
If Microsoft were to buy Opera it would effectively reduce the battle for browsers on Windows PCs to two contenders: Microsoft and the Mozilla Foundation.
