Because I'm jonesin', and I haven't completely answered the question yet...
I think we'll see the following in 1/48 scale released in this (or a very similar) order:
VF-1J Max w/ fast packs
VF-1J Millia w/ fast packs
VF-1A Kakizaki
VF-1A Cannon Fodder
VF-1S Max
VF-1D [i think this one is iffy, but if they could come up with an accurate sculpt, they could do the standard orange/tan VT-102 paint scheme, an Angel Birds liason ship, and a Virgin Road (Max 1J paint scheme). And if they wanted to get really cheeky, they'd release a low-vis 1D.]
VT-1 [again, iffy, but I think demand would be there if Yamato ventured it]
VE-1 [see above]
VF-1J Hikaru w/ GBP (they may release this as armor only like the first fast packs, but if the 1/60 is anything to go by, maybe not)
And then, what I would classify as totally doable if not likely:
VF-1A Max (TV)
VF-1A Kakizaki (TV)
Then possibly:
Macross 0
Macross Plus
Destroids
The only Zentradi/Meltrandi I can see them doing in 1/48 is an actual soldier- no power armor, no Glaug, no Regult, no Q-Rau.
