I see it like this...
What are you REALLY expecting June 15th? An Atmosphere release? Fine.
Lets assume for a moment it does release. What exactly, as an end user are you going to do with it?
Run backups on June 15th? Nope. Not going to happen on this date. No backup loader exists for Atmosphere yet.
Run homebrew? Erm... You can already do that with Hekate right now. And if you can develop homebrew, chances are you already have / are developing via Hekate, or helping with Atmosphere itself.
Which leaves Emunand and Game hacking / modding / datamining... Great. So you have your shiny new emunand tucked away on your Sd card (Sandisk/Transcend/Samsung/Takeyourbloodypick). What are you going to do with it on June 15th? Or maybe, you are DESPERATE to hack that game you are playing... (Pokemon or something? - don`t the tools exist already via that save editor? Or maybe you are DESPERATE for your battery to be resync`d because Linux messed it up.
So, while Atmosphere is very exciting for developers, NOTHING EXCITING FOR THE END USER WILL HAPPEN on release day. Unless you just like to look at new menu options or something.
I personally am looking forward to it, but I have realistic expectations for release day. I`m looking forward to checking out features and code and new possibilities and gradually doing some fun devving which I can already do now via Hekate. And a lot more features.
But I`m certainly not looking forward to the noob posts complaining that they can`t run their backups on June 15th.
That Thomhack boy is a classic example. And I stuck up for that twat before I realised he was a twat (how he was talking to Michael was disgusting).
So, tl;dr - don`t have too high expectations come June 15th if there is a release. If you are JUST a gamer, it will probably do little for you on this date. But if you are a dev, I get your excitement - but page after page of speculative crap doesn`t normally come from proper "devs". They already know the score by looking at the Github commits etc etc.
