Have any of you had your input bearing go "ka-boom"? (not literally)

I know mine is worn, is has been noisy for two years now but after my brother in law got stranded on the interstate with another transmission issue it got me thinking - how much longer do I have?

Its a 97 HX with 238K on it...I did the clutch 2 years ago, thought it was just the t/o bearing (clutch needed done anyway), didn't do my research, and here I am still with this other bearing noise, only to find out its the input bearing after everything was pulled, but still driving the heck out of this little car, hoping to get 300K out of it.
