I think physical games will remain. Sure, the console manufacturers and publishers want everbody to buy digital because it makes them the most profit. However, when we are at a point when 90% of people buying digital anyway, they don't really lose anything if they offer an optional disk drive for those 10% hardcore collectors. To keep their voices quiet and offer them what they want (i.e. physical media) will give the console manufacturers better PR than having those hardcores against them.
I also think that games on store shelves are welcome additional avertising. Honestly, avertising on e-shops have their limits. You can do promotions and special attentions all you want, there are simply too many games available in e-shops, they simply get forgotten. However, physical stores have limited space and therefore certain games can shine brighter on shelves than in the digital nirvana. Additionally, the bargain bins give attention to games that are long forgotten.
Another interesting development is the company Blaze with its divers retro consoles with physical media: Evercade, Capcom and Taito Superpocket, etc. It seems that their whole business strategy is built on retro consoles with physical media. I hope they will be successful.
