There are not many in storage anymore. However, A320 production will be increased to some 50-52 aircraft per month. This was supposed to happen in 2017, but was hold at 46 aircraft per month due to engine issues. Note that pre-FAL is already at 52 per month.
We should expect at least 624, 12*52, A320 family frames to be produced in 2018. Sill below 56 a month, 16TLS + 32XFW + 4BFM + 4TSN = 56. I expect the fourth line in XFW not being fully ramped up yet. Add some of the gliders standing around and it could be 650. This number can easily be higher, XFW could reach full production rate and TSN start ramping to five, that would mean rate 57 frames a month sometime next year, with rate 52 at the beginning of the year.
Add 90 A350, 66 A330, 12 A380.
That would make it 818 frames to be delivered next year.
