At Dicksmith's at least all the Vodafone handsets have been reduced by at least $100
The V1050 from Moto is $648 ($100 less)
The Nokia 6680 is $898 ($100 less)
The SE V600i is $648 ($100 less)
The SE V800i is $748 ($100 less) and
The Samsung V500 is $598 ($300 off its original price of $898)


Why?
Well Vodafone is launching 10 more handsets by Christmas and if you attended the roadshow then you would have seen some of the offerings extending the 3G and the Push to Talk ranges


3G
Sharp 703 1.3 megapixel clamshell with 8Mb internal memory and miniSD slot. BT & IR priced around $799

Sharp 903 3.2 Megapixel camera priced around $1349

Nokia N70

Motorola E770v

Samsung ZV10 - 3G handset with 50mb onboard, bluetooth and twin VGA cameras. A 3G handset under $500 priced at around $449

Motorola V3x - on show at the Vodafone Roadshow

Update:
Samsung ZV30 - 40mb on board and transflash , 1.3 megapixel primary camera, triband (cf. Z500v's quadband), bluetooth, ir. $749

Some questionables:
Nokia 6280
Nokia N90 - When will it arrive through official channels?
Sony Ericsson W900
Samsung ZV140


Non 3G

Sony Ericsson Z520i - Quadband flip with Bluetooth and VGA camera
Motorola SLVR - two different models
Motorola V360v - clamshell, PTT, VGA Cam, 5MB on board and transflash slot ~ $399

So if you are on the lookout for a Vodafone handset there will be good offerings, there is a trade in going on at the moment as some handsets are end of life ie: Sony Ericsson K700

You could even be critical and say that the Nokia 6680 is incredibly similar to the N70 and that the 6680's shelf life may be limited.
