Soon anyway... and some online retailers are promoting it as an ideal Mother's Day Gift. *cough* Walmart...
The Wii Fit Balance board retails for $89.99 and I may just have to pick this one up myself. When I saw it at E3 last year, the people lining up to try it weren't the 20 something young men, but the 30 something women with whom it struck a chord because the program they were running was the yoga and fitness program.
The little balancing game they were running was also interesting, and little trouble-maker me had to try something that alarmed the demonstrator. Instead of just leaning my weight to tilt the virtual board to get that ball rolling from one side to the other - I was on level 4 and there was a little hump between. I rolled it to the extreme other end then hopped on the other. Guess what? It worked. I batted the ball and it flew up into the air, over the hump onto the right side.
Go me!
