I finished it a few months ago after sinking 122 hours into it. By far my favourite JRPG of the generation and my favourite JRPG since Skies of Arcadia: Legends.
I can't wait for X, either, and I would definitely buy a Wii U to play it. The problem I have with Nintendo's strategy so far, is that they're announcing games that could be years away. I'm going to hold off until E3, by which point there should be enough already on shelves to justify buying a Wii U, and hopefully a clearer picture of what's coming out up until mid 2014.
But yes. Xenoblade Chronicles is utterly incredible. It's sold fairly well, and had a great critical reaction. I think it deserved plenty of GOTY awards, too, but was sadly overlooked.
