It will unlikely take that long, they put that number up because at the most that's how long it would take, if your case is complicated. But inland does take much longer then outland, I know a few Jamaicas that went home instead of waiting, because of how much longer it takes. But Shorty is right there is benefits of being inland, your fiancé can work while waiting here.
Also are you applying for Common-Law OR Spousal Sponsorship? I know applying as Common-Law will be a lot more work for someone rather then applying for Spousal. My suggestion would be marrying your fiancé and then putting in the application, it's a lot more harder to deny someone who is marred, then in a common law relationship, and you'll have to prove A lot more for Common law and will be scrutinize way more as well! Again this is just my opinion, if your planning on getting married soon, you should just wait until your married and then send it all in. But if your going the Common Law way here is an example of what you need,

I would start searching these threads and gathering your proof
And in regards to his Son coming here faster, it wont be. My friend( Who was sponsored from his wife) just finished his Son's Sponsorship, and it took the same average time as everyone else, currently 10 months, which really isn't that bad, but if your doing inland I think it will take longer then 10 months just considering that they are currently doing initial assessments for people applying in May 26 2014.
Welcome though, there is lots of help here, these ladies and gents are awesome!
