I don't think I would hold my breath!
802.11ac wireless isn't anywhere near being "common" yet so I cannot see any consumer grade giving these devices "free" for quite some time.
Many ISPs have only just moved to 802.11n so it will be "ages" before they move again.
And, of course, even if ISPs start to adopt 802.11ac devices they won't tend to replace them "for free".
If you want one you can always buy one!
