6E products access points won't be out for probably another 6 to 12 months at least (from any vendor), for actual sale (I know there are some beta tests going on currently though). And even then those will be the bleeding edge first gen units, and do you really want to be the guy that takes the beach? Anyone here not remember the MR45/55 debacle?
Clients I believe I've seen some Intel chips that are currently being beta tested, but those are probably also another 12 months out. Then the drivers, good lord I can only imagine how many issues and bugs they'll have.
Realistically, your looking at least another 24 months before there are a healthy choice of access points and clients that support 6GHz. If your desperate I'm sure you can get your hands on stuff in the next 12 months, but I'm not in any rush to discover the plethora of issues that will come with it. In the lab sure, but not in production 😃
