The improved SLAs come only when the applications are redesigned to take advantage of the improved availability of the underlying platforms. Multiple applications that share a redesigned component may get some shared improvements in SLA but only when the shared component is the SLA's problem child. Adding continuous availability to large applications (or systems of applications) that weren't designed around the concept takes a lot of time and effort (read "money"). And a lot of banks aren't too free with their money right now. An existing solution (even when based on antiquated technology) has strong appeal in the current financial climate.
