Read the press release this DS article is taken from and see if you can see the phrase "exclusive to/on Sky" anywhere.

and then see if you can see it on the original press release announcing the channel.

Whilst I doubt we'll get it in HD, I can't see the reason why we won't get the SD version. Sky customers will be happy with the HD exclusive, advertisers will be satisfied with the same exposure they get with the rest of the Sky channels.
I'm sorry, I wouldn't trust a DS article to confirm today's date, never mind the future carriage details of a television channel.
