no, it isn't, and it has no announced date.
Mario Party 8 is good. I liked it (could have been better, but it is the best thing out there and I got at least 100 hours of entertainment out of it) It is absolutely best with 3-4 people playing.
Mario Strikers Charged is tons of fun too. I would get that over Mario Party if they like soccer/football/whatever you want to call it. They can play brawl, so they should be able to play strikers no problem.
Mario & Sonic at the Olympics is supposedly good, but I've never played it myself.
Rayman Raving Rabbids 2 has 4 player simultaneous play, and I personally really liked the first, and I've heard the 2nd is just as good.
out of the ones I listed above, I would choose Mario Strikers Charged.
