Same problem here. I asked for a replacement of the right item, I'll see what they say:
Edit: They issued the RMA, which states the following:
If Newegg no longer carries an item that is sent in for replacement, or if that item is simply out of stock, the item will be sent to our Back-Order RMA Department. You will be notified via email of two options: 1) Newegg can send you a comparable replacement item, or 2) Newegg can issue you a refund at the current market value of the product. A current-market-value refund may not exceed the original invoice price. If the item is returned within 30 days of the original invoice date, a full refund will be issued.
