I have read the first six so far and I like it it adds alot of twisted fun to the mix. Lulu (I assume that its only logically him sence hes doing the same things as the last series just in a different style) still gets his geass but it makes him invincible and now Nunnally has a geass and a "witch" as her "dark side".
There is a "Irregular" military group made up of iindividual that seem to have geass as well. A real shocker for me was that Alice Nunnally's best friend is a member of the Irregulars. I thought she did the same sort of surveillance work as Rolo when she said see was watching the Milly (though I had doubt when I realized that she didnt know Nunnally was a princess as someone in that work would know).
The fanservice is pretty minimal really, a few panty shots and nunnallys naked in her KMF but nothing revealing (boobs and etc.)
I wonder if there is going to be a similarity between the relationship of Lulu and Suzaku in the first season of Lelouch of the rebellion, where Lulu and Suzaku are friends but enemies too

In conclusion I like the manga and hope that the series doesnt dispoint anyone.

The original Code Geass does have an ecchi side but this one's weird...
Panty shots on Nunnaly..err..and what's with the body change..O__Olll

I know it's kinda early to comment on the plot, but I'm confused who takes on the ZERO role..is it Nunnaly or Lelouch??

why change the body? giving back the eyesight is awesome, but if you change the person, then that kind of ruins the idea that it's nunnally. the body change just doesnt feel right and makes it feel like some sort of bad rip-off instead of an alternate telling
