On yesterday's stream Eddie said Poker should and will be coming to stake some time soon.
He didn't mention a specific time though.
I think that's a great idea. They basically get risk free money through collecting the rake. Having a super big player base this would be a HUGE opportunity for stake and for their players.
For people with skill at poker that might become a lucrative site. Many degen gamblers that just lost with casino games and sports might "try their luck" at poker, fishing time.

Unfortunately he seems to love to speak and announce many things but after that nothing happens for some reasons, especially when someone from the chat say one feature is missing during his live streams. But I wonder why they haven't already added it if they were interested in this matter. Even smaller casinos like Nitrobetting or Betnomi already have a poker room so it shouldn't be very hard for a big platform like Stake to create one.
This attitude reminds me of Elon Musk. You know Elon right? He is also good at making false promises but there are times he did it and then revised it. Don't know if he is confused or he is only playing tricks on us.
I think Eddie said it so that those peeps will hold on and continue playing on his site but they can always remind him again. If he still did not implement the feature, that should be the time for them to leave the casino. If they won't add it, it simply means they are not interested with it and they might be contented on what their existing features has to offer. Maybe they are earning decent with it?
So, why will they prioritize a single request coming from a normal user but as you said, there are casinos who has a poker room on them, so why can't the user go them instead? And maybe that is also the reason on why Eddie didn't bother making one.
