News:android 3.0 Gingerbread minimum requrements

Rumored that android 3.0 Features :

• Minimum hardware requirements for Android 3.0 devices are: 1GHZ CPU, 512MB or RAM, displays from 3.5” and higher.
• New 1280×760 resolution available for the devices with displays of 4” and higher.
• Completely revamped user interface. If you want to get a feeling of what Android 3.0 Gingerbread UX is like, check out the Gallery App on Nexus One. The same overall feel, light animated transitions,etc. Natively, through all the UI.
• Android’s split into 2 branches becomes official. 3.0 for top of the line/high end devices. Cheap, low-end mass market handsets will keep Android 2.1/2.2

HW minimum if such a thing could be said that many phones that have been issued previously could not enjoy this type.
But others say that
1 GHz CPU is recommended, not minimum.

So how exactly?
