They aren't removing jtag. You will still be able to do the boundary scan 
and programming with the 4 pin interface as today. They are going to add a 
1-wire debug interface using the reset pin. It wasn't clear if you will 
still be able to use the 4 pin debugging interface.

They are phasing out the jtagice box and shifting to a ice300 with similar 
capability and the 1-wire debug interface.

Hope that clears things up a bit.
