Eiyuu*Senki GOLD is a different game from Eiyuu Senki. When they announced the latter, everyone kept asking them for the former (because it has better game mechanics), so that's probably why they announced it. The story's completely different (and apparently better in the one they released), so the work they'll have to do is far more than last time (where some other company had already done the all-ages translation).
