Mainframes use Java. Mainframes use SAP. Mainframes use COBOL. Mainframes use web services. Mainframes get used with all sorts of applications and environments. IBM has been selling more MIPS almost every year, but the growth in MIPS is likely less than the increase from new hardware, so it is very possible that the actual number of mainframes being sold each year is going down. However, the number of boxes sold is not a very reliable indicator of the market for mainframes (and mainframe programmers). As I said, you need to decide where your interests are and then look to see where it make most sense to work -- if your interest in mostly in .NET or ASP programming then planning on a career in mainframes wouldn't make much sense.
