The current plan is to keep Perkle alive and replace PoW Perkle with a PoS chain. The current discussions are mostly around using cosmos-sdk and likely abandoning EVM for CosmWasm. We have been focused on building an indexing and alerting layer and have admittedly neglected Perkle for quite a while. Now that we have made some progress there I intend to pay more attention to what's next for Perkle.
As far as it being sidelined from the website, that has more to do with the PoW chain confusing investors and other users, and us not having a great argument for running a PoS Ethereum fork going forward.
