Yep, seems like local wireless is the way they're going. I agree that I wish they had online trading (I don't know if I'll know anyone in person who will be playing these games), but this is still better than nothing. I plan on getting games on multiple systems (I have a 3DS and a 3DS XL) so I can trade with myself to get around some of the limitations of non-wifi trading.
I must say, though, despite knowing people who had the games in real life back in the late '90s, my friends and I hardly ever actually traded. Almost all of us got the same version (Red), with the exception of one guy whose game became so badly glitched that the rest of us wouldn't get within ten feet of it with a link cable. I obtained trade evolutions later on, once I had more games (mainly after Gold came out; I did my GSC Pokedex, then had my internal battery on Gold where the Pokemon were located die, and then decided to go back and do Red, mainly trading with myself and one friend who still played).
