All Hearsay so far...
I am skeptical that KTM will discontinue their best selling bike. The KTM 990 fills in where the F800GS and Tiger 800XC were introduced (maybe even the reason these other bike came out , and the 1190 fills in where the big GS, the Ducati Multistrada, Tiger Explorer, Super Tenere, etc etc.
If you think about it, their product line is a bit thin compared to other companies...at least in the street. I think they are growing, and making good decisions about new development.
Now...they could do something about the heat management and tank venting for the 990.
