What's wrong with idiea to have more games in gog catalogue? Let's hope they will not abandon Tue and Thu new oldies
releases, and nothing will change for good old games fans.
It'll be a mess. If it's a separate site that can be ignored then that's fine but mixing the old and the new just makes a convoluted mess like other sites. I don't even think to search for old games on sites like gamersgate, I only ever look at the sales section.
Plus the new games market is more competitive and if they get games DRM free they're going to have to pay out a lot of money to keep them as exclusives, otherwise every distribution site will end up with them. If they do pay out for exclusivity then the prices are likely to be more than the DRM versions to cover the cost. If they don't pay out for exclusivity then bigger distributors will be able to sell the games DRM free too and undercut GOG, especially in sales.
...and in that highly unlikely scenario, GOG.com will be known as the DD that changed the rules of the game. Besides a solid fanbase of DRM-haters, they can always fall back on what they're currently doing: selling older titles DRM-free
