Do you have a source for that, or is the last statement also speculative? We're kind of going in circles here now, so unless someone can find new statements from the team members, or more gets released from the development bible in the future (more Sonic Origins extras, new artbook, random twitter dump, ect. ect.), that may be the last bit of useful info we could peruse short term. Again, as much as I'd love to discover a new beta with it, I'd be very surprised if many others even exist. I feel like the depths of searching Hidden Palace/DRX has gone to in order to recover all of what was found in Sonic Month 2019 shows there are very few stones left unturned. Especially when no journalist or publisher has EVER produced a picture of R2 in action (unlike most other zones we've hunted for).
