It's very unlikely that GPS will go away in 10 years.

So, at best you're looking at a slight upgrade - 2-3m error in position 
  to 1m or a bit less.

For most things, this isn't important.
You're not going to be walking round blindfolded in traffic, using tones 
to tell you left/right.

And DGPS can get you better positions with the existing hardware - at 
the cost of downloading a couple of hundred bytes.

Currently dual mode chipsets tend to be more expensive.
Eventually - P2 or so maybe it may be a good idea.
