The last update regarding SKY Arts HD was made as part of the following press release on the 05th August 2009 relating to Comedy Central HD.

"Virgin Media continues to expand its HD line-up with 26 channels launched so far, including E4 HD, ESPN HD, Film4 HD, Living HD, Sky Sports HD 1, Sky Sports HD 2 and a host of Sky Movies channels in HD. With further HD channels due to launch over the coming months, including Sky1 HD, Sky Arts HD and, now Comedy Central HD, Virgin Media will soon offer over 30 HD TV channels."
That was 5 months ago. Sure the release states channels are due to launch in the coming months and doesn't give a specific time scale however to me coming months means 3 or 4 months. What would have been more accurate is to suggest the channels will be coming in 2011.
If Virgin announce something, but the plans change, the decent thing to do would be to release a further announcement advising plans have changed etc... Too often we're told something will launch within a certain time frame, or something will come soon, then we're left hanging without any further updates. That's probably why this site is so popular, and the Coming Soon thread is the most read. People like to know what's happening, but the people we pay our money too aren't keeping us up to speed.
