I don't believe that and I don't understand what you said about mainframe.

SPARC is not a mainframe processor.

System Z (what you are calling 370) is actively developed and installed at
10s of thousands of sites as a primary machine. It's a lot easier to migrate
C code that runs on SPARC to Intel and replace a server farm than it is to
migrate assembler and COBOL that runs on IBM and there are advantages to IBM
OS and hardware that SPARC doesn't offer over its competition.

I personally liked SPARC well and am sorry to see it go especially since the
alternative is Intel. But go it will, and it won't take 20 years. System Z
on the other hand will be here for the foreseeable future. POWER will
probably also, but I know less about that.
