The idea of a new system, built like the old ones, with the same concept, no updates, cd's or anything, just the system and games developped for it (well now the only one that we know is "tiny knight" and look shitty...but maybe they'll do great games, I hope so)
Having the games on cartridge and the collectible aspect is really a big part of the vgs, plus it's not a shitty emulator with a rapsberry pi but a real console, something built and designed to play games specially made for it.
However it will certainly miserably fail, their communication is horrible, they change their mind every day and the price is just awful
