As other websites have pointed out, this time period is usually when Sega FES happens (not happening due to Coronavirus).
Multiple comments online also pointed out his belt seems to indicate it's Segata's son.
Message on the official website also says this:
Hello!! SEGA FANS
Ah! So you've come to this page.
You must really like Sega!?
Please wait a little longer until the site is open. ♪
More details on Siliconera and Gematsu.
Reminder that Segata died with the Saturn, even though he had some appearances since both irl and in a few games.
A Saturn-mini announcement would be pretty amazing, but it sounds like it might just be for marketing purposes too.
