Wireless speakers causing negative growth on Surround sound systems?

Hey guys,

Recently seen an article regarding consumer trends in the audio world. What I've read is that consumers are buying wireless systems rather than surround sound systems. This got me interested as being an owner of both systems (kind of with audio cast keys), it does seem that as people who aren't as interested in sound as me in my house are drawn more towards the wireless systems than they are the surround sound. What do you guys think? Do you think soundbars and wireless systems will slowly muscle surround sound systems out the way in the daily household?
