You can already add a 30 second video to Google My Business profile. This has been the case for 6 months or more. Google just provide the platform and tools. They do not get involved in content creation - video or photos.
In at least one previous post I have mentioned that between Google My Business, Youtube, Facebook, Yelp and websites/apps for specific verticals such as TripAdvisor WHY does the planet need another business listings platform?? With or without discounts. I would suggest that it is probably one of the most covered and competitive areas on the Internet and it will take a miricale for the proposed new app to get 1% of Googles traffic - even .0001%. To be honest, I could have just kept adding zeros and they still would not get it.
