The rumours of a new Helix might be because of the HUGE amount of facebook traffic wondering when the next software update is - it was supposed to drop last week but it's not ready.
That will be version 2.8.
The mods on the main group now shut down every thread asking about it, because there are hundreds of eijits asking every day!
But it's not hardware round the corner - it's another (free) software update.
