Geocaching Australia

I'm looking to upgrade my new Garmin handheld unit (was 600) but I see the 700 series is not around 3-4 years old.
According to Wikipedia these seem to historically be around 3 year cycles but I don't see any refresh or updated models?

Is Garmin moving out of this market or does it think these are as good as it gets?

I'd be interested to know the answer to this to. My 6 year old unit is due for replacement but there doesn't seem to have been a new model released for quite a while now.
