"per se" ("by itself"), not "per say"!
And yes, from an iPhoto point of view it's probably going to be a plus in functionality, overall. They might even take some advanced image algorithms from Aperture and make it "compatible for the masses" (e.g. you won't have much possibility to fine-tune the result, but rather have a "More-Less" kind of slider for the "effect").
But don't expect something of the calibre like Aperture - that is gone (and Apple made that clear by even announcing that they would "collaborate with Adobe to find a migration path towards Lightroom).

I wouldn't be surprised if the new Photos would be "iCloud only" - then we talk again about "free". Remember, you read it here first
