Can you personally (given your reading habits, income, etcetera) justify the price? If so jump in now.
This is just like a personal computer. No matter what you buy, within a couple of months there will be a 'better' one out. Never be surprised to see better features or a better price. But if you wait for it to settle down, you might be waiting five years from now. All you can do is be happy with the price and features you get at the point in time that you make the purchase. None of the current devices are perfect, but they are generally 'good enough'.
Now if you rarely read, or if you were just layed off, I would wait a bit
