Last Official BFL News I heard was shipping was estimated to start LATE October

Also they are not just shipping the items in the order they were pre-ordered.
I forgot the exact %'s but like 33% are shipping to Pre-orders, 33% are shipping to random orders, and 33% are shipping to Upgrades.

You also have to understand there are something like 15K pre-orders for the BFL-Product

If I was you, I'm guessing your running a 2,3 or 4 card system.
I would only keep 1 video card, but make sure its a 7970 or 7970x2 aka 7990.
That Way your hedging your risk, you can get some coins before the block reward change.
If BTC mining becomes unprofitable you can switch to LTC
If BFL or competitors ship a ASIC product within the next 1-6 months, and you can get it within 1-6 months.
Then you can still purchase a with the cash you saved on the cards your returned.

I'm not ANTI-BFL, I just don't drink the cool-aid
I would never purchase a product that has not been publicly Demonstrated and performance specs 3rd party tested
If my understand ASIC chip production, you don't really prototype the chip, you do it all virtually and then make a huge BATCH and hope for the best.
Unless you use a Multi-Project Wafers (MPW) to prototype your Chip, not all Fabs offer this.
If BFL had a working Prototype with a MPW ASIC chip, they would display the shit out of it.
Plus you also have to take into account that there currently shipping product is just another company's re-branded FPGA, and they originally said it was a custom built chip until someone proved them wrong.
I'm currently a GPU Miner, that will purchase a ASIC products on the open Market once they start to ship and there performance is verified.
Until a 3rd Party Tests one, I still consider it VaporWare.
