A handheld can't replicate Wii Sports.
Can it iterface with a Wiimote?
Can it wirelessly or via an HDMI out send a video signal to the TV?
If the answers there are yes, sure you could play Wii Sports on it for when "grandpa comes over" or whatever.
Not that I think Wii Sports is really all that important any more anyway. Yesterday's news. As expected Wii Sports Club isn't doing much for the Wii U. Bowling and Tennis gets old after 6 years.
