Chill out guys! The VF-1 line is coming very close to an end. I guess probably 4-5 more to go. A couple of Js and maybe an A.  
Uh, if there are 4-5 to go, that means we're not even halfway there.  LOL.  Or barely halfway. 
But, I'm in no rush.

The way I figure it, they potentially have 13 more canon VF-1 versions/paint schemes that they could release in 1/48 (if you count GPB as another version, then make it 14).  Admittedly, a few of the ones I came up with are unlikely candidates for toys.   
Edit:  I wasn't gonna list my speculative choices, but I'm too much of a geeky fan-boy not to (apparently).  From most likely releases to least likely (IMHO): 
1. VF-1J Max 
2. VF-1J Miria 
3. VF-1A CF 
4. GBP armor 
5. VF-1A Kakizaki (DYRL) 
6. VF-1S Max 
7. VT-1 Super Ostrich 
8. VE-1 Elint Seeker 
9. VF-1D 
10. VF-1A Max (TV) 
11. VF-1A Kakizaki (TV) 
12. VF-1A Angel Birds 
13. VF-1J CF 
14. VF-1D Virgin Road (Max 1J scheme) 
I'll bet if they took a few dollars of the price of a CF compared to other 1/48s, it'd sell a lot better than the 1/60 did.  Of course, I maintain that the deal with the 1/60 was that everyone was clamoring for a TRU Japan exclusive only to have a general release a few months later.
