When will Haswell be stable?

[iGlowstick]

Hi guys,

I've been doing lots of reading on here and have seen the basic suggestion of waiting for the new Haswell based CPUs (4xxx) instead of purchasing the current and slowly dying ones (3xxx).
I've also read that when new chipsets are released they are often buggy and will need BIOS revisions etc. in order to run better.
My questions are:
How long before the Haswell CPUs are truly stable, past BIOS revisions etc.?
How much of a hassle are BIOS revisions? (Simple, Tricky, Dangerous?)

I appreciate the help!

Figured I'd give this a bump in hopes of more insight.

Unknown. If you are really scared of instability, then in general you should wait 1 year before switching to a new CPU/motherboard (either AMD or Intel).
