I bought mine in April when the price (in the UK) was £~570 for the body & 18-55 bundle.
Luckily I was stateside when I got mine and managed to get another lens, a flash and some accessories for £~590 (converted from US$)
If you look at the bundle price a year before that, it was £~770.
The price currently here is £430.
It's technology, and like all new items, initial prices will be high, but as demand and sales picks up, prices eventually come down to a point where they will become stagnant (probably a price above the cost of manufacture).
My advice - when you have the finances to buy, just go out and do it - buy the best your budget allows.
If you wait, there will always be something bigger and better to tempt you away from what you're looking at.
And once you've bought it, accept the fact, you WILL see it cheaper somewhere else after a month or so... you'll weep a little too!!
