Shutter life/failure on the NEX's.....

Does anybody know how long the shutters are good for on these cameras? I intend to use HDR mode and some of the other shutter intensive modes on a regular basis as I have worked out this is the best way to achieve low ISO shooting with very good jpeg results. Has anybody had any early shutter failures to date? This is my only concern about the longevity of my 5n so far. If it lasts for a couple of years at least then I'll have had my moneys worth but if it goes in 6 months then I won't be too pleased. Have any intensive users had any drama's with their shutter's?
