As for the amount of zones, once you include artifact specific class quests that's like adding another zone, probably two in terms of assets, writing and art.
Also Blizz is probably already working on laying out the overall layout of the expansion after Legion too.
I'm not really happy with Blizzard taking so long either but neither do I think they are slacking off. In general the ways and speed at which we consume content are much faster now and they've removed tons of gating that kept players from consuming the content quickly. Things like attunements or how in BC you needed flying before you could even enter 3 of the dungeons and one of the raids unless you had a warlock friend in the guild.
We aren't getting any less content come Legion from everything I've seen. In general we are just much more efficient at getting the content that we have done.
Though I kind of throw up in my mouth a little to even refer to Tanaan as "content."
