Ah man...you have good taste in games, so I was hoping you'd be trying it out.
Still...can't really defend Nintendo on their limited edition nonsense...so if that's a big deal for you, it's understandable. Personally, I'd recommend Conquest at least, as it plays a lot more like the GBA and Tellius titles, and is a good challenge on top of that. Adding Birthright and Revelations as DLC are the same price as the limited edition, so you'd just be missing out on collector's stuff, which was kinda pointless in the U.S. If the special edition was out of stock, I wouldn't have had too much of problem with missing out on a book of portraits and a 3DS bag.
Again though...your call in the end. I do hope you get a chance to play it eventually though.
