Just taking a look at Tabke’s list of upcoming Pubcons, and there’s a couple missing from his number sequence:

So what happened to numbers 12 & 13?
Will one of them be the summer conference at a similar time to New Orleans last year?
How is Brett gonna squeeze in 2 conferences between February (Oz) and Spring (Feb/March/April - Boston)?
What about the normal London event, or will they name it .5 llike before?
