Ok it appears I got a little over-excited earlier with my math and what not.
I will definately be going, IF I get my contract extended in March / April.
I'm only contracted to then so I need to make sure that I have job stability beyond March / April before spending money on LAN's and plane tickets and things which I may not be able to use if my contract is not renewed.
I will definately be going though if I do get a new contract.
