Ok, since some of you are being a little thick and ignoring what I said, let me quote from that story.
"As you may know very well, with the PSP market, the situation is very different in Japan than outside of Japan," said Kitase when speaking to us at E3 2011. "We are having to be very very careful in how we decide what would be the best way to deliver the game to all the gamers."
Here's the important part:
"We are having to be very very careful in how we decide what would be the best way to deliver the game to all the gamers."
This is not "we may not release it at all", it's "we may not release it on PSP and if so we will port it to another platform
". Seriously, a first year Vita release would not surprise me, or at least a simultaneous release on PSP/Vita/other platforms.
... Come to think of it, just how big ARE 3DS cards? EDIT: Found my answer, up to 8GB. So, yeah, at worst it receives a 3DS port for the US that's exactly the same but with 3D effects stuck in.
