According to a recent post on the Petrol Station's Facebook page, James Watt from BrewDog will be there on March 17th and both Tactical Nuclear Penguin (32% ABV) and Sink The Bismarck (41% ABV and currently world's strongest beer) will be available.
As ridiculous as I think it is to produce beers with that high of an ABV, the beer geek in me can't help but want to know how they taste.

Update from the Petrol Station Facebook page:
We will have hardcore ipa on tap, isle of arran paradox on cask, tokyo in bottles plus free samples of sink the bismarck, tactical nuclear penguin and nanny state
