Sakura Wars 2017 (20th anniversary idea)

I'd interested Sakura Wars since late this March. Ratchet is my favorite and wondered.

Sakura Wars concludes 20th anniversary in 2016.
Sakura Wars musical is still progress in current, but no new games since 2008 when including any  new SW games. Excluding crossover appearances. (But only Project X Zone)

SaGa is no new installment since 2002, but revival in 2014 and released in 2015. Which is franchise concludes its 25th anniversary and named SaGa 2015.

Sakura Wars will get a revival in 20th anniversary conclusion.
I want this is developed by Square Enix.
The new installment is Sakura Wars VI, which takes in Berlin, Germany.
Some of seiyuu are replaced by new ones. Like as Lupin III 2011.
Seiyuu grows and older compared to original.
About Ratchet Altair, she sounds like aunt since her announcement, it called miscasting. (English dub doesn't count)
And new characters' seiyuu are much younger compared to current seiyuu, it needs to balancing ages.

Sakura Wars VI takes at 1929 (Some months later than Dramatic Dungeon, a year later than SW5).

Some of seiyuu are kept, but below characters on seiyuu are changed.
Sumire: Michie Tomizawa to Miyuki Sawashiro (1961 -> 1985)
>24 years younger. I heard that retiring about original one.
Ratchet: Akiko Kuno (1950 birth!) to Shizuka Ito (1950 -> 1980)
>30 years younger. Since original seiyuu is NOT professional seiyuu, it's just a musical actress.
Glycine: Saeko Shimazu to Hitomi Nabatame (1959 -> 1976)
>17 years younger.
Daisuke Gori is dead, who voiced in one of character in Sakura Wars. It needs to new replacement.

Kept that Sumire and Glycine are fine, but Ratchet is NOT fine.
She really need to the changed as new seiyuu, because voice actress is 64 years old woman in current. (Musical is progress, but new installment is coming yet.)

New characters: Usually 1984~1993 births.
I want see younger seiyuu (1999~2003 births) in Sakura Wars! (1999 is Sumire Morohoshi)
