There is zero benefit in waiting. Supose you had 1/3 of the hashing power and got it in the first second. You have a 1/3 chance of getting the extra block before someone else gets the first block and published risking your block.
However, if you publish the first block you still have a 1/3 chance of getting the next block first and ending up with 2 blocks. Thus waiting provides risk but zero gain.
In theory this changes if you can do a 51% attack, but that erodes trust in the block chain.
