A niche to Microsoft is a huge gaping hole to the rest of the world.

I like the statement about growing popularity of Linux on high performance 
clusters (hmmm. what's Linux replacing?)

It will all come down to support and integration... Will MS support the 
hardware interconnects (or, will the hardware vendors want to write MS 
drivers for their hardware)? Will MS provide decent hooks into their 
development environment (.NET, Visual Studio)?
How much of an ordeal will it be to take a useful code running on a Linux 
cluster and port it over to your shiny new Windows Server2003/HPC edition 
cluster? Is it just configure/make?  What will the licensing work like? If 
we change the hardware configuration, will WS2003/HPC need to "phone 
Redmond" to authorize?  Does WS2003 support NFS mount points? (Win2000 doesn't)

For "from scratch" development, it's probably not a real big deal which 
environment you develop for (assuming that they both "work"), and 
presumably, the OS isn't consuming the majority of the CPU cycles in either 
case.
