Indeed, it appears only the Vita twin pack was tracked on vgchartz and not the standalone FFX or FFX-2 SKUs, so the numbers are under. Include digital for both (which we sort of have, given that Famitsu gave out that info for January but not December) and they're both in the region of 280k-300k (if someone would take the time to add the numbers from Famitsu properly I'd be very grateful), with PS3 ahead by about 10k.

It would've at the consoles infancy.  People would have gravitated torwards the platform because the likely assumption would be that more are coming.  It's a bit late now with the reputation being established and all.  

I think having Type 0 and FFX HD as exclusives would have done awesome for Vita.  Hell look at how well FFXHD boosted sales for the platform this late in the game.  It was even a Multiplat and where did the hardware sales go... to the Vita.  

I think Type-0 could still do big things for Vita though as it's still basically an exclusive if it comes west, and it would put back at least one piece of the puzzle which made PSP do so well (namely exclusive big-name JRPGs like Crisis Core:FFVII, though of course it won't be as big in Japan where it's just a port, or the rest of the world for that matter being as the Vita install base is so little. It would still be good though) :)

I'm not sure that FFX-2 has a singular SKU for either platform.  I prefer to not add digital sales cause VGcharz doesn't track them.  Also we don't look like fanbois grasping at straws trying to make the platform look better than it is. Not that I don't think Vita has a higher than average download attach ratio.  Just that in most cases we can't prove it so why feed the flames.  

You're right to call out the fact that in Japan at least, digital accounts for very little (3%-5% even on Vita). However, seeing as we do have that information (especially because we do actually have all of it, it was actually November that was missing which is before it came out) it seems short-sighted not to include it (every little helps), plus FFX-2 definitely had a standalone SKU, even it didn't sell very much it still makes a difference when the margins are so small

If you take the latest Dengeki LTD number (227,301) plus the standalone FFX and FFX-2 SKU numbers from that siliconera article I linked (31,775 and 16,335, only as far as the second week so may actually be more now) and December + Digital sales (18,964) and you get 294,105

Add up all the available PS3 numbers from the same sources and it's 283,062 + 8,792 which equals 291,854, so basically parity

The PS3 version of Final Fantasy X HD has outsold the Vita version.

Some people want the game in HD, the Vita´s display isn´t HD and X doesn´t even run at native res on the Vita.

More options are better than less.

End.

Bolded is important.  

@Italicized part : really?  A lot of people would say that about the Vita.  In fact most people would probably say that the PS3 will still sell more going forward than the Vita.
