Could you remind me where I can find out the projected time of the next difficulty adjustment?

With current growth rates, it's about every 11 days. Next adjustment in about 5 days to 180M.

Also, can you provide some numbers or point me to a source to support your claim?

Thanks for your input.

Here's an optimistic estimate: http://mining.thegenesisblock.com/a/49a674a026

If it doesn't break even in the next 3-6 months, it never will.
