I don't get this "nerf" mentality. The Python is a 57Mcr ship, WITHOUT upgrades, and topping 130MCr when A-modded.
For 130MCr, I'd expect my ship to be pretty darn good.
There is no need to "balance" everything "in relation to the sidewinder", because the sidewinder (or any other ship for that matter) doesn't cost 130MCr when A-modded. Some cost more, some cost less, and therefore do not need to be balanced to the Python.
So I for one will be very surprised and disappointed if the Python is nerfed.
Who knows on the Fer de lance? Until it comes out, no one.
