Sounds like a BIG serve of Codex Creep to me LoLI've heard that hormagaunts will be 6 points without additional biomarphs and normal gaunts 3 without weapons but including WON (meaning they get 1 point cheaper and get won for free). hormagaunts can buy WON for the same cost as termigaunts can do now.
warriors can be taken in every slot. normally you can take them as HQ/elite as now. wings make them FA, a tyrant as a HQ (maybe a higher tiered one?) makes them troops, heavy support have +1t, +1sv and each can take a "heavy" weapon.
stealers are going to be elite unless you take a broodlord (who can supposedly be upgraded much more than the current one.).
one of the new HQs is said to allow ripper swars to controll objectives (malantrope?).
tyranids have supposedly got ahold of an alpha+ level psyker and integrated his DNA into the swarm meaning they will have about as many psychic powers to choose from as space marines (and they are all assumed to "make world wolf look like a child's game").
take from this what you like but I've heard it from a nid-nut who runs a GW store. imho especially the thing about ndis beeing ubar-psyker seams odd but would tune in with all the anti-psyker gear the wolves got. maybe they will need it?
dispelling every psychic pwoer on 4+ isnt that ridiculous if each one not dispelled costs you a whole squad...
maybe the change the malanetropes fluff to also be a super-zoa?
