Two of these I wished to see canon, but didn't unfortunatley!
The other two (NaLu, and LuNa) I can definitely see the horizon spreading for them both especially with NaLu!
Natsu still playing games about Lucy? He need to stop playing and get with her already. Honestly though, I always prefer them getting together at the end. To me, thats always the biggest goal. Naruto finally getting Sakura at the end would be his biggest dream come true. You would feel the positive emotions of him finally getting her. So, I dont care how long Hiro takes, , long as it happens.
