Technically there has to be a MGS5 yet, as Kojima the other month on Twitter wrote that TPP is "MGSV, not MGS5"; thus by his word GZ and TPP are not a break in the numerical series with roman number, but just a title with "V" the letter (I suppose as a reference to Venom Snake, which in the opening of TPP is directly referenced as just "V").

Said that, I personally would like to see more Solidus.
