I was just offered a brand new 27" LED replacement for a twice fixed 24"! This sounded to me like the new 27" with Thunderbolt is def coming out (getting "rid" of stock)
Even the chap I spoke to was impressed with my deduction although never let on 
PS: amazing customer service from Apple though - this is why I will keep on coming back to Apple time and time again !
