I am going to be the first to shed some serious doubt on these rumors and normally I would pass on this one. However, there are a couple interesting things listed in here, so I thought I would throw down this morning.
The poster of the rumor was posting for the first time (credibility sinking), and was posting in English when it obviously was not his first language (credibility sinking faster).
Just a side note though, several rumor mongers are jumping on the bandwagon of a August/ September release for this codex, including saying they have seen the playtest codex. from posts by Harry, ghost21 and Bramgaunt.
Please take tons of salt here, and if you are able to decipher some of the vague parts of these rumors, please comment on.
Warriors, now come with a squad leader 'Prime' - eh , like a sergeant, PW (think staff of light - but A2), stat line now looks like a Boy... a 3+ boy... 80 squad 10.
Gauss. Same rules but counts as AP1 on a 6 - only on vehicle.
Phase out: will now be once a unit is reduced to 25% of its initital numbers, it phases out
WBB: basically a 4+ fnp, Str 8 wont auto kill, str 9+ does. ap1 does, ap2, 3 no effect
Flayed are troops, 2a, reduce ld to 5! also DS into cover
Wraiths, cost 4 pts more, have pw
many weapons have Nec at the start, guess who wrote the dex.
1 New vehicles, Pylon. Pylon is a AV12 turrnet which can pile plate or move 'Necrons' next to it
mon is now LR price, but better...
Destroyers now pick as a group to fire S6AP4H3 or S9AP2H1
Tomb spiders have 4 variants, 40pt base. 1variant is basically a tervi but only produces base scarabs
army is very very mobile, but not is a get in a box and move way.
