I don't believe this.
New players are the reason why we have had Basic since the start, so that people can actually play the game with ZERO books to buy.
If that's not enough, they can buy the PHB.
A "new" player that finds that the PHB with 12 classes, 9 races, 13 backgrounds, and 30+ subclasses are still not enough is a petty pretentious new player... or is not a "new" player at all. In either case, they can buy two books instead of one. So what are the reprints really for? For that really petty pretentious new player who has PHB+SCAG but wants something also from XGE, or has PHB+XGE but wants something also from SCAG? So pratically someone who wants to use 3 books but only buy 2? And to make him save 50$, we are paying a tax? :/
Well, as I said I don't want to believe this, but thinking back at what happened in 3.5 where everybody was asking to be sold again hundreds of prestige classes with little to no changes because they wanted "official updates", maybe I should believe that D&D gamers really like paying taxes.
