4 volumes released to date from Dengeki. One manga chapter has been released in G Fantasy magazine just this month. I could be wrong, but I foresee this to overshoot SAO in future. The guy does look a little like Ichika from IS even though the illustrators are different.
Well, it's the anime made by SUNRISE by the way. Sometimes the stories can be cheesy & can be senseless. But don't expect this much until it fully airs just like the other animes like My HiME/Otome, Gundam series & so on.
