Google Galaxy Nexus Phone II soon?

According to rumours, the eight month old Google Nexus (Sell for $349 on US Google Play Store) will get updated. The processor will be upgraded from 1.2 GHz to 1.5 GHz. Both front and back camera get upgrade too. Also it will support expandable SD card.

I bought Google Nexus recently from Google Play Store and in general happy with it except the batter life (have to charge daily and can not sustain one day medium use). The processor and camera upgrades are not important to me. Actually, faster processor may make battery life worse. I hope the upgrade (GT-i9260) also include the battery upgrade (from 1750mhA to 2000 mhA). Currently, the genuine 2000 mhA battery with slightly thick cover sells $40-50 dollars. It is too expensive.  2000 mhA battery should be stock battery.
