Okay, I promised - PROMISED -myself I would stay away from WP 7.8 update posts until better information came out. But I never-NEVER- believed it would just be the start screen. Paul Thurrott came out with his claim based on the off hand statement during the developers announcement of WP 8 because that is all they CONFIRMED was coming. But the term "features" was used. I am not a smart guy and am stuck with a public education (from North Fort Myers Florida, none the less, so I got sun baked), but I did learn the "s" on the end of words means "more than one".
While I am also still eating crow in some circles due to proclaiming over and over that at least the 2nd gen devices (Titan and T2, Focus Flash, "S", so on) would get Wp 8, I am still not buying the start screen only bull-snot. So, I did a little digging, and came across this atricle:
Post details what features WP7 won't be getting | Electronista
This is a leak from a power point presentation to mobile executives that state some of the features that will not be coming (Wallet hub, true multi-tasking, some more detailed device management, encrytption features, NFC, ECT). But it does state some decent updates will certainly be coming (dozens of camera upgrades, some Nokia-powered features I can only guess at such as Play, Drive, Lecture).
I have seen no other rumors, so I will not put any more cheese on my foot to be consumed later. If I do not buy the one rumor from Mr. Thurott, I can put no more stock in this other unproven rumor.
But I will be this bold and make 3 predictions:
1) It WILL be a legitimate upgrade
2) It WILL NOT just be one feature
3) We will still all want WP 8 devices anyways.
