I don't think the trackpad is any louder than my late 2011. I don't think there is anything cheap sounding about the new model. it is just a different sound. The response of the trackpad is firm. Saying the trackpad sounds cheap because the sound is different and one you don't like, doesn't make sense, in my opinion.
I thought the trackpad on my new 15" was loud until I went back and tried my 2012 rMBP. It is much louder. I don't think I even noticed that the new trackpad was loud until I read it here and it definitely doesn't not sound cheap in my opinion.
