Canon Pixma PRO9000 Mark II: safe buy

Hello,

I see this printer for quite good deals around the net now that Canon has announced a new model. It can be had for about $250 or so (after taxes).

Since it is a relatively old model, I imagine it is going to be discontinued very soon and I am worried Canon may stop update the drivers and softwares for the printer. I wonder what is Canon's history in this regard. Do they continue supporting their discontinued products?

How does it compare to Epson R2400? How is the Epson support?

Thanks.
