I am sure there will be a market in the future. Maybe not for small architectural companies or single family house owners. But the big developers of large residential projects, soccer stadiums, theaters, museums, what ever costs money will make a use of it. With VR you can not only show apartments but also explain and test large interior or exterior space. You want to see how a the view from a seat in a stadium is? Use VR with Oculus Rift and it will blow you away. There are endless possibilities.
I started to promote this kind of service on my webpage (Service for Architekturvisualisierung) and already have customers which are awaiting April when the Oculus Rift (hopefully) hits the market.
