Crafty Answer: They are more flithy now than anytime since '06; we just don't get to see it on TV.
Course that's not the spirit of the OP's question. (In fact, this thread is the babeshow fans' version of a "Does my bum look big in this?!" Basically it has only one intended response!) So my take on that...
It really should be a pretty obvious fact that the channels will never again look like they did pre-2011. Pervcam was the final nail in that coffin.
Left to their own devices, the channel's current way of operating is unlikely to change to any real significant extent. And from their pov why should it? Censorship is, of course, spot with this, things simply work for them the way they are atm.
Any changes will only come with the opportunity to make more cash. The channels not currently cutting it for some on here is absolutely zero reason for them to do anything any differently given that almost every single change suggested on this board offers no evidence of bringing them extra return. Worse many suggestions would likely work contrary to that.
MARCEE's summation of the shows' history is a pretty accurate one I think. I'd just add two things though:
1. When you hear babes, etc., speak of the pre-2011 era it is largely done with an element of frustration at how the period is held in such high regard by some punters. The perspective is perhaps indicative of a sense that simply too much was given a way for free during those times (and that, maybe, people on the shows got carried away with the partying atmosphere onscreen also?)
It seems to me that the time is looked at as a naive one where things were unformulated and the wrong things emphasised.
2. IMO the infighting that reputedly went on between operators during the 'Golden Age' speaks to the fact that a fair few of the bosses were not happy with their output being dragged in a certain direction by the 'rogue' element that was Bang Babes.
Thereafter the introduction of Ofcom's code gave the remaining operators an excuse to reset. Eventually they took full advantage and forged the predominate business model that exists (with the odd tweak) to this day. In other words, they wised up.
As for the OP's secondary and perhaps more interesting question: What are the chances of any 'improvements'? Well the answer to that can only realistically lie in another: What's the chances of commercial imperatives dictating the need for a move in that direction? And the answer there must surely be in the media context surrounding the shows - i.e. Ofcom's rules (despite much self-censorship a regulatory back stop is still the ultimate hinderance to change IMO) and the standard of direct competition in the 900s (this too is largely dictated by Ofcom's setting of the arena in which the channels operate). In other words, things would need to move on from the channels looking for opportunities to change, to that change becoming a commercial necessity... They'd need their commercial arms twisted a bit!
If Ofcom fail to fall to some mighty scandal or other (it's hard to imagine any other likely scenario despatching them I feel) a slow erosion of censorship may be all we can realistically hope for. Each successive survey of public opinion Ofcom carry out may well offer less scope for the maintenance of their draconian code. (The channels will of course still have to find a commercial advantage to taking up any permitted changes.)
A larger sea-change in regulation might well bring about greater competition closer to home for the channels. Depending on what form that took that might actually bring about some real impact on the shows.
It all quite a delicate balance between what's permitted, what's commercially advantagous and what is expected by the public. Change in any one can effect the others to some degree.
