user30546: I am bit new with bitcoin. I run a electronics/software company in China and Australia. I would like to create new bitcoin mining hardware. The specs are as follows:
The miner is PCI-E installed, runs in a normal PC case or rack sized server around 200w, latest 28nm chip, around 200GHash/s, selling $99 (USD).
I will buy the chip from existing supplier. The design and manufacturing will be done myself.
Given I have a hardware team that have done many ARM Soc applications, and a reasonable experienced software people with Linux and software.  
My question is it worthwhile the effort to do it? Is it profitable and what if any are the perceptive pitfalls?

user23123: Depends on whether you can bring something to market that's better than what's already out there. I'm not sure how quickly you can set up something like that, but 200GH/s for $99 right now would probably sell decently. 12 months from now, probably not so much.
This is really an economics question you have to answer, and we'd need a lot more information about your costs and market in order to assess the opportunity properly.
