If Turbine sticks to lore, as they should no you will not see female dwarves out and about in Middle Earth.
(Gods help, wikipedia is the only thing I can find to quote):
"Male dwarves were overprotective of their women whom they sheltered from other races. Few female dwarves were seen by other races, hence the myth of Men which lead to the belief that Dwarves grow out of stone (supported by the fact that both male and female Dwarves looked similar). In addition, no more than one third of the dwarven population was female, and few men took wives because they were too busy in the mines. The female dwarves too are reluctant to marry males that they do not like. Often, if a dwarven female has her eye on a particular dwarven male, and if she cannot have him, she will accept no other. As a result, they had a slow population growth rate and the attrition caused by the many wars they fought would take many years to recover from, if ever. They dwindled after the Fourth Age like the Elves, until Men were the only of the great races left to rule Middle-earth."
