Is the PB actively marketed in countries where PAL is the standard (I know, rhetorical question, it isn't really 'actively' marketed anywhere is it...)? Considering Roku is a USA company, I'd bet a VERY high proportion of existing customers don't even know what PAL is, let alone care if the PB supports it. It WOULD be a nice feature to have, as I've got quite a few PAL DVD's that I can't play any more since my region-free DVD player died and new one doesn't have a hack, BUT, the vast majority of customers would be better served by fixes to other stuff. I sincerely HOPE they wouldn't hold up releasing a beta (or final) that fixes many other things solely because PAL doesn't work good.
