I've never regretted my 3DS purchase, but it occurred to me that I haven't really been wowed by any recent 3DS releases. I passed on Smash Bros. for 3DS because the Wii U version seemed better and I've basically never played local/online MP on my 3DS. Code Name S.T.E.A.M. was alright, but I absolutely can't blame anybody for skipping it, it's not a must play. The best thing I can think of was Box Boy, which was great.
It seems like a far cry from the days of Super Mario 3D Land, Fire Emblem Awakening, Luigi's Mansion 2, Mario Kart 7, Bravely Default, Zelda: Link Between Worlds. The local co-op Zelda will only be for specific people, and the new Fire Emblem is still a little way off. Honesty not sure if there are any other upcoming releases I should be looking forward to.
