You can't really look at it that way with a GPS unit. They aren't like computers where you have to keep up with mainstream for compatibility reasons and such. What GPS you buy now will continue to do what it does until it blows up. And better isn't always better. In 16 years of being in the computer business I have NEVER seen a more powerfull computer come out 6 months later and be half the price of it's predecessor, but I'll have to take your word for it I guess. Even so, better is deceiving because most people will never see the difference between a 1.2 and a 1.8 chip or an additional 512 of ram.
I have yet to see this situation with GPS units. The new ones will always be more expensive because the technology is seems to always be new. Unless you compare the top model of last year with the lower model of this year. Lower models tend to contain older already developed features. So I can see how the model you buy last year is now a different model, but $100 cheaper this year, but it's comparable features and not any better. And the model that is better is most likely $100+ more expensive then what you paid last year. Even so a GPS can only do so much and that last year model will still do what it did without any loss of functionality. Heck, you can already pretty much get everything possible on a GPS. MP3, Video, Camera... it's all available. The only thing really left is chip speed which will always be progressing and you'll never keep up. Delorme pn-40 is the first, I believe, to introduce dual chips which allows one for GPS and the other for map generation. This makes it capable of streaming aerial images as you drive and sat connection is really quick. Of course, it's a handheld, but it does have the ability to autoroute using TOPO.
One new thing that is starting to happen is Internet Access. This will revolution GPS. However, it's without question that it's all about the service fees and I'm not interested in another $20/month fee so that feature is irrelevant to me.
Anyway, you are far better off getting a GPS with the features you want now and not getting caught up in irrelevant gimics of future devices.
Unless, of course, you simply prefer to keep up with the latest and greatest. But, if that was the case, you wouldn't be looking for a $200 unit.
