A friend of mine also studies Wing Tsun, combining it successfully with Aikido. We spend a few minutes after Aikido class, analysing the WT techniques and thier similarities to Aikido. I've attended a class of WT aswell, and there are some major similarities, I agree.
If you have time, as Jun said, do drop by an Aikido dojo to give it a try. Life's too short to miss out!
