We've asked around about ATI's recently announced low-end products and found out the paper launched RV710 is going to hit retail in the next week or so.
This is what most people who hope to make money on them have been told. The demand is there, but we believe that Nvidia will pull out a stunt and drop the price of Geforce 9500GT, taking away some breathing space for the Radeon HD 4550.
The slower of the two RV710 cards, Radeon HD 4350, will come at a later date, but you should expect it in retail / etail by the end of the month.
We believe most cards went to OEMs and that this delay in shipping is not related to a production issue.
