Why does it matter about the lack of Microsoft's support for Windows XP? Just because Microsoft drop support for XP doesn't mean that everyone will stop using it between now and April 2014, it isn't like the old days where Windows 98 really was outdated, bug-ridden and with severe limitations when it came to modern software.
Also, MAME cabinet owners might get shitty if they have to pull everything out and/or reinstall another OS just because their newly updated MAME crashes on load or errors out back to the desktop (in fact, they are probably more likely to just revert to the last version which worked with XP - assuming the up-to-date ones and not that cobweb-ridden Slot 1 (Pentium 2/3) board running DOS MAME and a handful of "golden era" games).
