Yes. If you don't, you'll be kicking yourself down the road.
If you like your model, ask for a price reduction since it's obviously now lower in price (your older model).
I play one game really. An emulated version of everquest (http://www.shardsofdalaya.com). I dont see it as being a problem since its an older game with a new twist but just wanted opinions.
just called my store and they didn't have any yet but it sounded like she thought maybe later tonight. I'm returning my iMac I bought last week for a rMBP, so I'll update in here if they have them when I stop by later.

I bought mine even later than you. I knew there was a refresh but my old pc died and I was desperate. This is also my first ever OSX machine so I was always going to be hugely impressed, Haswell or not. I don't regret it whatsoever. My only niggle: The arrow buttons are so damn tiny!
