Of course it will keep. The alcohol acts as a preservative. Personally, I think draught Guinness tastes better than bottled and you can sling the canned stuff in the rubbish bin. However, if you want it at home bottled it has to be.
I have some bottles of Mackeson (similar to Guinness but slightly sweeter) in the cupboard that I bought for last year's Christmas puddings and I will use the bottles up in October when I make this year's puddings. That's if I haven't used them in casseroles before then.
