How soon do you think we'll see re-scaled TDA?

[Urauloth]

I like the terminator plastic kits we have for Heresy, I have 5 guys in each pattern and I plan to build them regardless of what GW might do in the future because they're nice models. However, I'm going to want more Cataphractii for my DA at some point, and while I'm perfectly happy building the ones that are hanging around my mountain of grey plastic, I'm a little nervous about the idea of buying any more when they might be upscaled at some point soon.

 

I think it's reasonable to assume this will probably happen, as Heresy TDA kits are trailing their 40k counterparts in size (the new loyalist Indomitus kit is obviously colossal, but a Cataphract looks like he lapsed on his space gym membership if you put him next to a Chaos terminator). Saturnine armour also looks like a big step up in size even without the giant egg shoulders.
There's also that preview image on WarCom of what looks like a terminator packing a volkite charger - that might be a character model, I suppose, but it seems awfully like a tease for a new TDA kit, and it's painted as an Iron Warrior which suggests it's part of the same release cycle as Saturnine and the upcoming breachers etc.

 

What do you expect, and what are you doing yourselves?
