It'd be nice but as said before seems unlikely at this point given they already confirmed there will be no final launch details at E3. September we'll probably be finding out (hopefully) about lineup, price ect.
They probably have decided on date and a price range, but want to gauge E3 reception before nailing the price down. Then they'll probably announce the price in late July either at the investor meeting or on Nintendo Direct; two months before launch as usual.
