Will staking rewards increase after the ETH2 merge?

Right now stakers are getting ~7% return but will that amount increase after POW is eliminated?

I saw someone post last week saying that returns could be as high as 25% after the merge because stakers will be getting the rewards that are currently going to miners.

But I haven’t seen anyone else back that up. (IIRC, this claim came from an ETH2 developer. Can’t find the thread…)

Anyone know if the staking rewards will increase after ETH2 and POS take over?
