Let's not speculate. No one knows for sure what Avov will do, but themselves. Even if they update their current firmware to not work with Stalker middleware, you can run Kodi, and without modification, you can continue to connect to their servers. Avov and Infomir (the creator of Stalker middleware) are competitors in the IPTV space, they want to sell their boxes, and maybe Avov feels that they need have their own middleware offering to survive against Infomir and other box makers. That doesn't preclude Papaio from creating a different portal for NOVA, especially if Papaio wants to maintain its user base.
