Foreseeing Summer Sale (+Nuuvem)

(Late topic just a few hours from the sale starting - but consider this a hype post only a little different; Even if steam sales were worse the whole event thing makes me ansious and i need to do something. Anyway if the sale does involve surprises or timed events we will already have a topic for wanabe seers)

Sales aren't the same. Steam made progressive questionable changes, some forced to.
Nobody expects a hit. Everybody expects a smaller return to previous sales (discounting steams steady growth).

Am i the only one that thinks thats why this sale things will change?
Im not saying it will be great but for weeks i have this feeling that they will try to shake things up- main reason being momentum and, lo and behold, competitivity.
If i were on the sales board that would be my view; Steam knows its been loosing points and buyers from the recent changes and obviously are more then aware about the growing slices other stores and resellers are getting. A lackluster sale would only confirm the feeling of 'buy anywhere else' and their higher spending customers would simply spend their budget elsewhere before the next sale. Any change they make have almost 6 months to start showing returns- once it was a habit to hold wallet for a steam sale budget and thats where they have been loosing ground. Any stellar sale will have better returns but a fraction of what could be if buyers were expecting and saving for the big event.

So risking loosing more faith in a particularly bad moment (come on, we know it helps against stolen cards but region locking and gift changing is unanimously bad) while others grow... steamworks was genius and the service is great but they risk having most keys sold elsewhere and still taking the server load. My bet is they know they have to step up their game somehow.

Any wild guesses? Predictions?
The whole sticker thing also gives me some hope - but i can hardly guess what they're gona do. Good guesses?

PS:
Btw, speaking of competition, while GoG and Humble went pre-steam sale Nuuvem is trying to catch buyers from the summer sale by starting the sale 4 days later. They released a table of prices beforehand with many titles 'still in negotiation' - meaning 'waiting for steam prices so we can (try to) beat then'. Wich is good news to my ears.
So if you can buy and activate from south america this is will be handy:
