The ban lists are made to sell new cards more than anything
Anyway the gist of the upcoming link format is that pendulum zones are now shared with the 5 regular spell/trap zones, so pendulum users get less space, and summoning from the extra deck is severely limited unless you make use of the new link monsters; without using links. you can only control a single monster summoned from the extra deck at a time. This very much limits anyone that doesn't buy link monsters, and will very much weaken if not completely obliterate many archetypes. To make things worse, links won't slow down power creep at all like some hoped, since OCG players are already making dumb turn 1 fields with it like triple firewall dragon very easily. So it just seems like a cash grsb that will kill many decks and make some cards worthless.
