Just an FYI, the Amazon pre orders are first come first in line. So if you want a Hybrid card it would be wise to place your order now instead of waiting for it to be in stock. You won't be charged until it ships.
While I wish there was more stock, this pre order process is much easier than having to deal with nowinstock.com alerts. Also, I am sure it makes things easier for Amazon since they can better determine demand.
Also, lol the Hybrid was in stock at Newegg for a whopping 9 minutes today. This reminds of the days trying to get a PS3 at launch in NY. It was just about impossible. I ended up going to Middle of Nowhere Virginia.
