Not just "I want Housing", or "I think it would be a good idea..."
No.
I think Blizzard is being STUPID.
Everyone wants to point to Warlords of Draenor, like it was some sort of "real attempt" at a housing system. It wasn't; it was half-assed, and anyone who has even TOUCHED another MMO could look at Garrisons and see, there was zero passion behind it. Nothing about it was fun or interesting, it didn't offer any ACTUAL personal customization. Everyone's Garrisons were identical.
I think a real, legit Housing system -- especially something that allows you to see other players' houses easily (like FFXIV's system, albeit fairly restrictive) -- would not only satisfying a real, long-standing demand players have had, but would actually attract players *back* to WoW.
Hell, you could even springboard an entire profession off of it, like Carpentry (hell, even introduce Lumberjack/Woodcutting as a new gathering skill), focused exclusively towards building tons of house-items. And of course, you could have various bosses throughout the entire game drop new items, trophies, even leverage something like Archaeology for additional stuff.
Personally? I would give each player a single "island" to build their house and decorate to their hearts content, and have a limited number of "premium" houses throughout the game, which would be unique to that server. So maybe, while everyone has access to a house of SOME kind, the coolest houses would be ones based in specific locations, like Hrothgar's Landing (just north of the Argent Tournament in Icecrown), or maybe one of those previously-inaccessible houses places somewhere in the mountains of the world.
But even if it's just totally instanced-off "islands", I still think there would be a huge draw. Just let players visit the "islands" of other players, either in their guild, friends list, or even a "visit random house".
I dunno. I just really think Blizzard is fucking up by NOT adding a proper, fully-fledged housing system. It might not be EVERYONE'S cup of tea, but I think the MMO industry has proven that Housing, as a feature, is here to stay and not a fluke. It would just give players an additional layer of "things they can do" when they log in.
Just... don't add any GAMEPLAY-affecting reasons to have a House. No "buffs", no "free/extra resources", just an ENTIRELY OPTIONAL thing. Because nothing makes things less fun that feeling *obligated* to do them.
