I honestly doubt they'll make any of these supposed "changes" they've promised us for 2016. The producers have practically slaughtered the format with BB15 and BB16 within the space of a year. And now they're slowly taking the celebrity version (which is far more successful for C5) down the same road. I mean look at how much nominations meddling CBB17 has had ffs.
They need to take the show back to how it was in 2012/13 (because lets face it, C5 BB will never be like the 2004-2006 days), so might as well revert to a time when it was partly successful and actually watchable in the C5 era. It's the disgusting production that's killing the show most. Stop with the constant nominations twist. Let them nominate each week in the DR, in private. No tasks/twists to save favourites, no immunity, etc.
BASICALLY NOTHING LIKE HOW BB15, BB16, CBB16, AND CBB17's NOMINATIONS SYSTEM WORKED. Just housemates going into the Diary Room and giving two names and reasons every week. Maybe one or two rounds of Face to Face Nominations in the series, but not every single ****ing time.
The casting also needs to be WAAY better. The thing is with C5 recently, is that they tend to cast people who fit into a particular role/stereotype. You have your token flamboyant gay guy (your Mark's and Aaron's), the token black woman (Your Toya's and Adjoa's), the argumentative, brash, opinionated, "honest/tell it like it is" bitch (Your Helen's and Sarah's), a few vacuous, fame-hungry men or male models who have "connections with z-listers as dull and devoid of any personality as themselves" (Your typical Winston's, Ash, Danny, etc etc), the odd idiot who wants a career in Politics of some sort (yet actually risk going on a tacky reality show like Big Brother....in 2015. yeah chase those dreams

), (Your Steven's and Joel's etc), the odd slapper here and there (Your Biannca's, Danielle's, and Harry's), a posh twat who went to a boarding school and probably thinks they are above the rest of the fifteen gaudy buffoons, they're going to be spending their next few weeks living with. The odd old and/or kooky person who's triple the age of the rest of the house shoved in just to add a little diversity, when it really doesn't whatsoever (Your Pauline's, Eileen's, Simon's etc etc). And then some.
The tasks are also seriously lacking. Previous series have had some good tasks which I don't see why they can't be re-used, nowadays it's just tipping a bucket of gunge over someone, guessing who called who a twat, eating/drinking something disgusting. All of which just makes bottom of the barrel television. What happened to those tasks that required housemates to stay up overnight, or the ones which lasted four days long. Honestly, recycle some old tasks and be more ****ing creative than oh, I don't know, telling the housemates to rank themselves on podiums every ****ing series based on what the public has voted on a poll as the 'MOST GENUINE, MOST UNTRUSTWORTHY, etc etc'

(don't even get me started on the "HOWEVER, THIS WAS NOT THE REAL TASK" secret missions)
I don't mind having one or two big twists in the series like C4 used to have. But only if they're planning to fix the highly flawed nomination format that the show has adapted over the past 2 years. And please for the love of god NO SECRET ROOMS. They've been done to death so much since 2013, that they've virtually ran out of names for thing and have even resorted to calling it "The not-so-secret room" in the last edition of bloody thing.
But because C5 are stupid. They won't take any notice of the above ^ and we'll probably get another BB16. So yaay
