when will sony develop native wireless flash system like Canon

Canon's got the 600EXRX wireless triggered flash and the new native wireless trigger with full TTL metering and ratio control etc.

Do you think Sony will ever catch up in this regard?  The A77 had the over-exposure problem and the A99's hotshoe adapter is problematic when working with anything other than the new HVL 60 flash.  Though I'd really hate to switch to Canon due to the lower spec sensor and no live-view + swivel screen for the full frame cameras... arrrggh
