Looks like my prediction was wrong. Twitter being vague again saying they "hope" this is one of the last few weekends.
Getting more pessimistic about the release each day, especially with Sega and their prior actions. Kinda expecting Sega to repeat 2012 again. Announce for the west, show off an English version at PAX then go silent and not respond to anyone. The fact they are not releasing any info at all, especially for the PC version, and just vague garbage(on twitter no less) on an 8 year old game is really surprising.
Hoping I am wrong and somehow they start open beta next week with PC players included. But with COVID-19 fear rampant in Japan, schools closing, and Sega of Japan is doing the changes, I wouldn't be surprised if they pushed the beta back till the very end of Spring or just flat out delay it indefinitely.
