Here is my predictions, mainly based on opinion polls in Clarin and at Wikipedia and on the provincial elections results earlier this year in some states.
For the chamber of deputies, I think it will be:
Juntos 60
FDT 49
AL 4 (2 each in BA and the capital)
Vamos 3 (In BA)
HPC 3 (Cordoba)
FRC 2 (Misiones)
FAP 2 (Santa Fe)
FIT 1 (BA)
JSRN 1 (Río Negro)
MPN 1 (Nequen)
UPS 1 (Salta)
My predictions here were very accurate as well. The results:
Juntos 61
FDT 48
AL 4
FIT 4
HPC 3 (Cordoba)
MPN 2 (Nequen)
FRC 1 (Misiones)
FAP 1 (Santa Fe)
Vamos 1
JSRN 1 (Río Negro)
SEPRSC 1 (Santa Cruz)
