After the long-awaited Canon 600EX-RT was announced alongside the Canon 5D Mark III earlier this year, we knew it would only be a matter of time before Canon dropped more radio transmitting Speedlites in the lineup.  Now, Canon Rumors has word that a 430EX II replacement is inbound for possibly a Fall 2012 announcement.

For those not ready to cough up nearly $60o for the 6ooEX-RT Speedlite, a 430EX II replacement should come with a more enthusiast-friendly price tag (likely in the $300-$400 price range).  Perhaps we'll see an unveiling of the new flash at or around Photokina 2012.

Stay tuned.
