Eh, I'm a bit ambivalent at the moment. Maybe if and when it's official I'll feel differently, but when I woke up to the news of the first axe in 2009 I was devastated. Not so today.
If anything I'll be more sad about the fact C5 didn't allow it to at least reach its 20th series...little things like that kind annoy me, but then that it just typical of their appalling channel so. If it is axed again I don't even expect there to be a proper goodbye either (like another UBB), if the contract isn't being negotiated until the autumn (as some of the articles have implied) then it might end up being a case of 'oh yeah the last series was the last sorry bye the house is being demolished tomorrow'
Whenever it's axed again I think it'll sink in more the following year, we never ended up having a calendar year off after it finished on C4. It's just become so routine now that it'll be weird to finally not have it on.
