with 4 hms gone this week the 9 left could be cycled out by the end of June. This twist will lose viewers all those that supported the stitched up hms. I reckon this could easily reach 100k viewers maybe more. Ch5 can get more viewers for reruns of popular shows so maybe they will cut their loses to protect their brand with advertisers.
Even if it doesn't happen I bet it has or will be discussed sooner rather than later.
Can this series be saved? I don't think so.

It would be nice to think that an ignominious end is in store for this BB.... and for the morons running it.

They'll definitely see it out until the end. They are still going to get more viewers than any of their shows so they won't cancel the series. Beyond this series though i have no idea what will happen.
