Konami has opened up the official Japanese website for eBASEBALL Powerful Pro Yakyuu 2020, which launches in Japan on July 9th, 2020. The regular version of the game is priced at ¥7,678, and a digital only “Powerful Edition” will be priced at ¥9,878. We aren't quite sure what's included in the Powerful Edition just yet, but those details should be available soon.
The website also confirms that amiibo are supported in the game. It's likely amiibo tied to Konami, like Simon and Richter, will have some sort of special interaction.
