Uber Suit
*The Tau uber suit is called "Riptide"

NEW UNITS
*Mek Tank – Sporting a giant Shokk Attack Gun, firing Bomb Squigs. Tank can purchase a KFF.
UNIT UPDATES
*Flashgits - Their Snazz guns roll for random range each turn (12+3d6). On a triple 1 they overheat like Gets Hot. The unit may purchase upgrades like +1 BS, +1A, blast, rapid fire, skyfire, ans others, several are mutually exclusive.
*Boys - cheaper!
*Meks - Look for ability to field an increased number of Deffdreads and Kanns than currently.
*Stormboyz - Gain a "Rocket boost" attack that can target flyers. They must move 18” and if they pass a flyer they each get 2 attacks on it as if assaulting a vehicle. Move as infantry during their next turn. Looks like the designers played a lot of THQ's Space Marine!
*Buggys / Trakks - May tank shock if they are upgraded with spiked plates/wheels.

Part 2 from Larry Vela
NEW HQs
*"Grot Boss" Grot with a stateline of a Ork Boy, but higher BS. Equipped with a nice kustom-mega-shoota as an option. Can also get a Buggy or take a Killa-kan as a transport/upgrade
*"Da Crew"  An HQ unit of even bigger Nobs. They have odd LoS modifications, One Nob must be nominated as "Da Boss", and if Da Boss is killed, one of Da Crew is promoted.  This interacts in some new way with "Kill the Warlord" victory conditions, and is effectively an entire "warlord unit".
NEW UNITS
*Grot Whirlybird:  Rotored transport: Capacity 20 Grots. They get dumped on the battlefield roughly from the Whirlybird taking a mandatory DT test, and cause mayhem if they fall atop another unit.
*Grots Buggys: Similar to Nob Bikers, but are buggies with Grots on the back and Orks behind the wheel! Drive-by attacks. Highly likely this will be an "alternate unit" for a buggy combo-unit box.

Gretchin/ Grots
This bit came in to me over on Faeit 212 by two separate sources, and its not completely clear whether the following will be in the Ork codex, or if it will be part of an allied supplement that may be coming.

Part 1
*I dont think this is for a new Orks Codex, or a new Codex at all yet though.
*grot boss - a big grot almost an ork.
*Gretchin Weirdling - grot psyker. Lvl1. Upgrade to lvl 2. Access to divination, gork, and mork lists
*Killa kans in elite.
*Gretchin - can take control collars no ork herder like in ork list. 5-20 unit. Cheaper than ork codex gretchin by a pt. Can take whirlybird or looted wagon as dt
*Squig runts- sounds like 40k equivalent of squig hoppers
*Whirlybird – looks like a Huey hit with ork hammer, bomb doors underneath to drop gretchin
*Grot scootas - rocket propelled skateboarders? Squad of 5-10. Hvy bolter profile weapon.
*Grot buggies - drive by assault 8 grot blastas
*Grot rocket - single shot roket with large range and big blast.
*Big Guns – control collar option again, the ones from ork codex, plus a flakk gun with skyfire

Part 2
*Grot Whirlybird -
*Looks like a old Vietname War Hellicopter, big bulged bubble cockpit/body, skinny tail boom.
*About twice as big as the ork DefKoptas. Concept is the doors of the main body open on the
bottom like an old bomber to drop the Grots on to the battlefield.
*Cannot carry Orks or Bulky/Very Bulky models.
*Can drop Grots at any point along path travelled in movement phase only if not Zooming.
*Placement like deepstrike, but scatter is reduced if hovering.

What is Currently in Playtesting
This is always exciting when you get a chance to know what armies are in the playtest cycles right now. To my surprise, Imperial Guard, and Black Templar are the most dominant that we really did not know about. Of course there are Eldar and Orks, which seems rather plausible right now as well.

Another highlight...... No Tyranids. Perhaps playtesting is done with them now......
