That's an ingame canon view/explanation. I can understand the down scaling on the mechanized walkers for treaded vehicles and other things such as that, but we still should see some more elements of TS technology in TW units, like how they reused the Rail Guns for the Mammoth Mark 3/27. Scrapping full body suits for generic infantry are a joke though, and they can't use the whole 'downgrading for cost' excuse because that's like giving our troops in Iraq chainmail armour instead of ceramic plates because it's 'cheaper'. Suicide. By generally looking at TW's art theme, it's just pointing to that EA's designers are focusing on a TD'ish' throwback (you know, aside from the whole Scrin thing! ). Granted, it's a futuristic, teched up TD'ish' throwback, but a general throwback none the less.
