Do not get your hopes up too high... Eddie promise new features and new gambling sites to people in restricted countries, every streaming session ...and it seldom happens.
He is creating content and these things might be in the planning phases, but nowhere ready for implementation. He even laugh at himself, when he makes promises like this... but let's see what happens.
Most of their budget goes into marketing and not into development of new features.... just look at the time that a new original game were last, launched.

I think there is a difference between a new game and a new feature.
A new original game doesn't bring new players, a new feature like poker would 100% do.
Besides poker and casino, poker would be the 3rd leg of the site. Other than the costs for development and hosting there is also no risk of losses in this area. Lean back and collect rake.
Also, he didn't laugh or whatever when he spoke about it. He actually sounded pretty serious.
Of course it does. Original game is new in the eye of the gamblers so they will get curious to try it and who knows? They might like it and it can now be one of their favorite games. Poker is not a feature but it's called a game. One example of feature is the chatbox or the notification bell. A new feature can excite a gambler and it can enhance their existing experience so it is helpful too if the casino will came up with it.
Stake is a big casino so don't worry about the development and hosting fees. They can surely afford these. It seems clear to me that this was a stand alone poker game or category, just like sports betting. It made sense since I know there are already several poker games on Stake.
