Well, they can't still be an army for new players and people who hate tactics since they aren't that in the first place. They are more forgiving than some armies, so they aren't unfriendly with new players, but they are definitely a tactical army, and trust me, I've played several, I know.
As to when it's coming out, not for several years, probably. The Necrons are one of the newer codices, and as it is GW doesn't put them out very quickly anyway. It won't be in the near future, at any rate, though with the help of a big campaign, we might get some new units or a campaign-specific codex like the Speed Freaks for the Orks.
Also, for future reference, try not to use internet-speak abbreviations on the board. If you want to use the word "see", type out see, instead of the letter c. Thank you.
