Zero Question

Things i conclude from Zero :
Each route in Zero contribute to milky way crossing.
for example Rinascimento Okabe only have "world can be deceived" piece without knowing how and Vega Okabe only have "Mayuri and suzuha is necessary to make okabe back to his senses" piece

Later on they will pass the piece onto the next "Zero Okabe"
Maybe there is Okabe who will find "how to deceive the world" piece or "Metal upa is the key item" piece.
So there are lots and lots of Zero Okabe stories that left uncovered.

Once the piece are completed, Thats the milky way crossing worldline

My question :
1. Did you reach the same conclusion with me? or am i missing something.
2. Could those "Uncovered Pieces" will be explained further on some kind of sequels material in the future? (you know some kind of milking to the franchise, too)
