The reason Blizzard doesn't want to open too many new realms is the fear that many of them might end up empty after the "day one interest" winds down. And the reason Blizzard doesn't want to increase total server size is fear that maybe the amount of players won't drop enough before Phase 2, when Layering is supposed to be removed.
As Blizzard begins to reduce the number of layers on a realm, they'll start doing nightly server maintenance, restarting the server and reducing the number of layers. Eventually, Blizzard will slowly reduce the number of layers until there is only one per realm.
While Blizzard can technically handle the overcrowded realms and the login queues, the reason they shared so many warning posts hoping to convince players to move to other realms, was only because Blizzard wanted a smooth launch for as many people as possible. They were hoping to spread the population evenly across all the realms, to prevent longer login queues.
Ion Hazzikostas is quoted as saying the queue cap is "around 30,000". Ion warns players that if you come home from work and find yourself in a queue, around 12,000th or 19,000th, that you won't be playing that night. Blizzard assumes that players facing those queues will just go to a different realm.
Resumen:
Blizzard teme el efecto día 1 por tanto no van a abrir mas servidores.
Cada noche mantenimiento REINICIANDO los servidores y reduciendo las capas adiciones en los servidores desde YA.
Blizzard ya aviso que los reinos sobrepoblados seria un problema entrar a jugar y como ya estabais avisados se lavan las manos, culpa vuestra por quedaros en un servidor sobrepoblado, esperan que la gente se canse y vayan cambiado ellos mismo de reino a reinos mas despoblados.
El máximo de QUEUE de un servidor es 30000 y da un supuesto, si llegas a casa de trabajar y estas en la cola entre las posiciones 12000 o 19000 NO VAS A JUGAR ESA NOCHE y te dicen que lo mejor que puedes hacer es cambiarte de Reino.
