Definitely. Right now the page cache on x86 has a limit (per file) of 2^32 * PAGE_SIZE == 2^32 * 2^12 = 2^44 = 16TB. And I doubt that will change. x86 will be going 64bit in the next 2-3 years, at which point I don't see it paying to push 32bit code into the larger data sizes. Especially when we our limit is still 2 orders of magnitude larger then the largest disk manufactured today.
Now the file size limit on x86 can be increased a little by increasing the internal PAGE_SIZE for the page cache but that will only give us a bit or two which really isn't significant.
