Languages change. It's normal. It can be a bit sad when a distinctive sound stops being used in any language.
a slight nasality may be dertected
I had noticed that it is either absent or fully pronounced. If someone is speaking normally, -ę will be -e, but in careful speech, it will be pronounced as -ę rather than some half-hearted attempt somewhere between the two. I heard it today when someone was trying to teach me a new word (which I have since forgotten).
What is the verdict as of today's date in AD 2008?
It's not really for me to pass judgment, but I'd prefer it to stay.
