"Unnamed sources quoted" has not been the case, in Android forums here, there and everywhere.
One name that comes up is Verizon rep Brenda Raney. She is quoted several times over a period of months in 2009. One of her remarks reported at phonearena.com (which has been posted here before):
"Verizon spokesperson Brenda Raney said, "The Droid Eris currently using Android 1.5, can and will be upgraded to newer a Android operating system
software in first quarter 2010. The enhancement will allow customers to continue to enjoy the powerful HTC Sense experience while also gaining the additional benefits of Google Maps Navigation."
The "first quarter of 2010" ends on the 31st of March. It's only the 18th of March in my hemisphere.
One misleading problem is that the sites and blogs that report these quotes seem to need to marble it all in with a lot of speculation on their part and rumors they concoct unilaterally; that does not help, they should just leave the quotes as-is and knock off the rumor mongering, in my opinion.
