It doesn't really matter if this season of Walking Dead has been slow.
All they need to do at this point is imitate the sets of the house to the settings of the show and add Walkers.... Boom! they are done.
Seriously that's it, we will see the inside of a church, terminus again, more rooms that look like a forest, Noah's house, a couple of rooms from the hospital
(that dark pit at the bottom of the hospital) the gates outside the hospital, Atlanta streets again, the new place they got to.. the new gates,
they could basically recycle some of the sets from the house in 2012 and not only would it fit with season 5 but most people wouldn't recognize the same rooms since it's been so long. they have more than enough sets to make a new house from this season
I don't even question it at this point... it will come back, they would be fools not to bring it back, it Has to come back. walking dead must come back for the sake of profit,
And personally i would be glad if they brought it back if they were able to use Rick, Michonne and Daryl. It's been 3 years and I am still waiting to see the official characters make it to the park. To be honest I find it kind of pathetic that they couldn't get them (imagine the purge without the lady in blue of the polite stranger, imagine resident evil without Leon or Jill...)
I would be okay with a zone or two. Just as long as they hire as many actors for the zone as they did for the house. one of the problems I had with the zones in 2013 was that they felt kind of empty for being the zombie Apocalypse. or a small house. I think they will try to make a mage house again but I really hope they don't. just a normal house would be good enough.
(I actually enjoyed the 2013 smaller house a lot more than the mega house from last year, the smaller size made the house more enjoyable)
