Exact? By the numbers you posted they most certainly aren't. Read 'em again.
Functionality? You mean throwing lead really really fast? Yeah, that's all guns.
Look? Seriously? If you scrape the name off a hundred 1911s, you could easily get them confused. But confuse this gun for a Kel-tec? Apparently you're easy to fool. About the only thing it looks like is a bloated LCP.
Feel? Again, so you have shot one?
Exact? You're right. They're off by a few thousands of an inch and tenths of an ounce. Clearly, that is just a conicidence. Ruger obviously used the .50 Desert Eagle as the starting point for this gun, and wound up within a hair's breadth of the PF-9.
Functionality? 10+1 9mm DAO semi-autos that easily fit inside a pants pocket ain't a dime a dozen. If you want to use "throwing lead" as the baseline, compare the LC9 to a Ma Duece, because hey, they both throw lead!
Look? So if Ruger copied the 1911, it'd be cool, but heaven help them if they copy someone else? And by the way, a PF-9 looks like a bloated P3AT, so it's no surprise that the LCP looks like a bloated P3AT.
Feel? I've shot exactly as many rounds thru it as anyone else here: Zero.

Of those, which does the new Ruger resemble most?
Again, I have no problem with finding a good gun and copying it, as it makes good business sense to have someone else iron out the wrinkles first. What I don't understand is why so many people here think this gun sprang into being without any precedence: I think it's a good gun and will be very popular.
But "revolutionary" ?
Hardly.
