You can bet your bottom dollar that devs will embrace the new non-destructive plugin model. It's a much better way of doing things.

It all depends on the level of editing in this new app, you mention yourself there's scant information. Many people are jumping to the conclusion that all the plug-in makers are frothing at the mouth over this. We'll have to wait and see how much editing capability will be in there and what apple will allow, for plug-ins.

I agree with the cloud and the cost, though I think it will be the default location just like many of its other apps. Apple will be pushing cloud storage over local storage, for the very reason you are complaining the cost, i.e., apple see this as a revenue stream.

This much actually is known... providing you like editing with RAW images.

The new RAW processor in Yosemite allows edit effects to be daisy-chained together extremely efficiently and - importantly - allows for 3rd party non-destructive plugins to be inserted into the processing chain as required. This opens up massive potential for all OS X image editing apps, not just Photos. Not to mention, some big improvements to existing filters like noise reduction.

Some of this was demonstrated in the recent Apple Developers conference. It's fast, powerful, and open to 3rd party plugin developers. Far superior to anything Apple have provided before in terms of image processing.
 
But that all depends on if the application such as photos (or what ever it will be called) will make use of that functionality. Its one thing to say the OS has APIs/services, its quite another to say any given unreleased app will fully leverage those.

I'm not disagreeing with you, but rather pointing out, we'll not really know until such time that apple provides the details.

A couple of developers at the Developers conference threw together a demonstration app to show how the new RAW processor API works, and how custom filters are easily plumbed in. I find it inconceivable that the Photos for OS X, which won't be released for many months yet, would not make use of the same features. Of course, we will have to wait and see, and version 1.0 will likely be wanting in many respects.
