Ugh...
Am I the only one who's getting annoyed at all the idiots wanting Sakura to die? Yes, she isn't a fighter, but how does that make her useless? She's a very very VERY talented medical ninja and is on her way to succeeding Tsunade in that field. She's skilled in creating antidotes, poisons, and has the ability to save lives.
Shikamaru isn't the strongest shinobi either, but I think everybody would agree he's an invaluable asset to Konoha. It's because he has other things that make up for his mediocre offensive abilities.
Sakura is the exact same case. She doesn't fight but she can still save lives. I don't understand why everyone thinks medical ninjas are useless. If it wasn't for a certain medical ninja all the people in Konoha would have been killed by Pain's Shinra Tensei. Yes, I know what you're gonna say, "blah blah... if we had someone like the 3rd Hokage he would have beat Pain...blah blah". Well the fact is we didn't, and Tsunade was all we had at that moment and she saved the entire village.
Anyways, to get back to the thread's topic,
Even though it may not be exciting, it's obvious she will eventually summon Katsuya. It was also mentioned a LONG time ago that Sakura had the potential to be even greater than Tsunade. She was originally a genjutsu type. I always wanted her to be trained by Kurenai in genjutsu. Don't know how that's gonna happen any time soon though =/
