It happened just last year spiking to above $1000 November-December 2013, so it can happen fairly easily.
No one knows for sure when it will, whether it takes a major news event, just some major volume day on exchanges...I'm just going to throw my guess in there.
April - June 2015. Book it!

Lets hope your guess is right it would be perfect time for it.
First summer holiday are starting in that period (perfect time for parting)
Lots of location planing so good esteemed for price.
