Will Bitcoin move to proof of Stake? Does anyone know? What are the developers opinions on this matter?
Nope, it won't - that's one reason why we like BTC so much 
If anyone or the team can modify the protocols, it leaves doubt to investors that its not decentralize.
You can check Bitcoin's open source code: https://github.com/bitcoin/bitcoinAs you can see, there are currently 819 contributors, meaning Bitcoin does get modified by various developers, here are the BIPs that have been proposed and implemented over the years: https://github.com/bitcoin/bips/.
However, any change that is added to the code must be backed by the decentralized node and miner community. Since nodes independently 'vote' which blocks and transactions are accepted, they can thus essentially refute a BIP for example. So without the support of majority of the network, developers can't change Bitcoin BTC.
There was no news about this. Moreover I think that Bitcoin is not developing any more, so it is doomed to be unchangeable. When some people say that they want Bitcoin to be greener they don't mean Proof-Of-Stake, they are talking about renewable energy for mining. Moreover, you can look at Ethereum, it is a long-long process that has not finished yet and we are still waiting for Ethereum 2.0.
As explained above, Bitcoin does develop, check the GitHub and version history: https://bitcoincore.org/en/releases/.
