More on this - following info was by a kind soul in the Yahoo MT group:-
Here are the spreads before and after the announcement.
EURUSD, GBPJPY, USDJPY, GBPCHF and AUDJPY are the only ones to reduce.
The others had the commission taken away but the spread was increased.
Code:

USDCAD 5 5
EURUSD 4 2
GBPUSD 4 4
USDCHF 4 4
AUDUSD 5 5
GBPJPY 9 8

Not entirely fireworks but looks like still a few more pips in our pockets
