Some Users Confused About Windows Phone 7.8 Update...

...says Paul Thurrott from WinSuperSite.com:

"When Microsoft announced its Windows Phone 7.8 update for existing customers—required because it will not support upgrading those devices to Windows Phone 8—the company probably thought it was doing the right thing. Unfortunately, some people are still confused about what exactly this update will bring to existing devices, and whether there might be more than just the new Start screen.

Based on a pre-briefing with Microsoft last week, I wrote Windows Phone 7.8 Preview, which details exactly what’s included in Windows Phone 7.8, at least according to Microsoft. But some users are still insisting—via email, Twitter, and other channels--that Microsoft’s language during the Windows Phone Summit last week suggests that there’s more to come. [...]"

He goes on to explain that Microsoft only promised to bring the new start screen from WP8.0 tp WP7.8 and that there was nothing in the presentation nor in the pre-summit briefing to suggest there is more to come besides new apps from Nokia for Lumia phones:

I think what he writes seems to be correct based on the wording from the presentation.
