You are really considering this as true? even as "maybe true"? LOL
That's some fanboy random wishes.

• Gregale? That's the codename for OS2006, Maemo 2.2
• They had no MeeGo team. Sotiris Makrygiannis and their team left Nokia on June 31, 2012.
• They had the wrong boss. He would never let this happen, Contractual obligations especifically bans any Linux based operating system.
• Maemo/MeeGo never target OMAP5. OMAP5 platform is still in development, no one device exists with that.
• "Amazing things to come". The word "Amazing" is used for Lumia marketing.
• PureView technology is currently only supported in Symbian, in one device (Nokia 808 PureView). Rumors exists that work in progress to extend this to Windows Phone, but not in MeeGo.

So... FAKE
