Considering they increased Armoury Chest space in 4.0 because we got new jobs, I'd expect the same thing to happen again. Personal inventory not so sure about, but the Saddlebag seems like the easiest thing to increase but obviously that has its own limitations. Retainers who knows, I'd like more inventory space on current ones as opposed to more free retainers but if they give us more then is better then nothing. The Dresser is expected to get some improvements so that should be the main thing for your glamour stuff.
