if they are indeed releasing a plastic Thunderhawk, I may pick one up...unless the price is comparable to FW...then I would just drop the money to get the FW one. Either way, hoping it will only cost a reasonable amount...cant wait for it to come out though.
I'd still get the plastic then, less of a chance of warping or being too heavy to stay upright properly....generally a better deal typically.
That said I'm not sold on this being a Plastic Thunderhawk just yet. Forgeworld stuff has popped up in GW battle reports since the reboot and even some of the pictures, it's only a matter of time before we see them teasing use with them in the Parting Shot.
I'm not saying it's not a Plastic Thunderhawk, I'm just not putting all my hopes into a picture GW is using to cocktease my wallet.
