I found that if it was just one spoke that went, usually replacing it and bringing the spoke up to tension will put the wheel pretty much back into true.
I had problems with the rear wheel on my new SCR2, which began breaking spokes after a week and kept doing so. It's been back at Halfrauds' HO to be completely rebuilt for well over a month and a half. They promised me a quick turnaround....

Now the Bike2Work team aren't even answering my emails asking for an update on progress !!
But I digress - you may be lucky and you'll replace the one spoke and all will be well. You may be unlucky and another may go in a few days' time, then another and another.
I went out and bought myself some Aksiums in anticipation of Halfrauds being frugal with the truth of their repair timescales, and I'm so glad I did. It feels like a completely different bike, and a much smoother ride.
