DD, I have been watching this as well,
and perhaps you are why those pages take forever to load ...
I ponder a few explanations, but no nothing.
1. Dell has been carrying the Wave products on their site owing to the absence of an established Wave sales/reseller network. Perhaps Dell didn't enjoy getting Embassy questions, perhaps Wave didn't like their cut, and in either of those cases, Wave products are movingto its various other resellers (which we've seen PRed a fair bit lately).
2. Dell is done with Wave. That needs an 8-k, and there isn't one. Furthermore, the Dell revs show only signs of growing, although again what makes a dollar a Dell dollar is rather obscure.
3. Its all still there but Wave branding has been subordinated. The only way to know this is to order a bloody machine and see. It may include the concept that Wave products have been somehow merges into other things, but I really have no idea how that would work.
I guess one could call to order a machine and ask what's included. Not my cup of tea, yours? (I don't speak Czech very well, and here in the republic, I'm not sure what the word for "Dell" or "Embassy" is, and worry that talking about Embassies may get me a visit).
The above content is my opinion.
