since HKD had peg USD for many years, there is a chance that HKD have been over valued. Once its unpegged, it might be depreciated to 1 USD to 10 HKD.

That could certainly be a potential problem, and I am not well-versed enough in economics and finance to tell whether the HKD is over-valued. But one other failure of the tying the HKD to the USD is that the economic cycles between HK (and to a certain extend, China) and the US are mis-matched. The US economy is doing rather poorly, but HK's economy is doing relatively well. But because the currencies are tied, the US's fiscal policies (including the interest rates) are hurting HK badly, and HK has lost one of the biggest tools (interest rate control) to protect its own economy.
Overall, I see more benefits in ditching the USD pegging than to keep it. But again, I won't claim to be an expert in these areas.
