Auto focus lag - Startup slow - A99

From my 30mn testing of the A99 the current (firmware 1.0) interface is noticeably slower than the A700/A900. Many aspects (power on, settings update after control dial rotation, menu scrolling, EVF to LCD switch time, viewfinder blackout even when settings effect and preview turned off) looked a bit too slow and, for functions present on both cameras, noticeably slower than on the A900. I've seen quite a number of similar reports here and on dyxum, too.
