Globalfoundries wants to be able to court that business, and not all of it (in fact a rather small percentage of it) is leading edge business.
Having a 45/40nm bulk Si process available next year still gets you (the foundry, not you you the person) early enough to market that you get to court after probably 90-95% of the 40nm volume that will eventually develop in the foundry space.
Checkout
slide 8 (revenue by technology) of TSMC's 2Q09 earnings presentation to see what I'm talking about.
All that existing revenue volume you see there at 55nm and larger is potential customer revenue for 40nm (for TSMC, for UMC, for GF, for any foundry at the right price) as those customers slowly migrate their product lines to the smaller process technology.
I use TSMC as the example because they report their revenue by technology in such a nice way, and they represent about 60-70% of the foundry market by revenue so they are a good proxy of what is out there for GF to "steal" away as they grow their customer base.
ilkhan I went ahead and pulled the data and graphed it in a way that I hope better communicates why I say Globalfoundries pursuit of establishing a bulk 45/40nm process flow has opportunity to grab a healthy chunk of the global annual foundry revenues even if it isn't ready for another year yet.
Graph of TSMC's Revenue by Node over the past 12 yrs
First thing to notice is just how much existing revenue is derived from what we enthusiasts consider to be decade old technology...look at the 0.15um numbers, heck even look at how much revenue still ships on 90nm.
Now notice just how tiny of a blip 45nm has made to date in that upper right hand corner. Compare that to the tiny blip that 65nm was just 2 yrs prior. Now look at
how little the revenue by node landscape changed in the 2yrs since 65nm (and 55nm) was introduced. In 2yrs that 65nm process tech at best snagged about 25-26% of the revenue for TSMC, the rest of their business was quite happy to stick with the older more mature technologies.
So how much of this revenue by node landscape can we really expect to change over the next year or two? At best it will change by the same amount as it did in the past two. Meaning whenever Globalfoundries brings their bulk 45/40nm process online there will be PLENTY of customers out there still on 65nm and older technology to go courting after as they slowly transition some of their products to 45/40nm node tech.
As for legitimizing my previous claim that analyzing TSMC revenue data is a good proxy for estimating attributes of the global foundry market as whole, here is the most recent iSuppli foundry rankings by revenue:

And the chart at the bottom of this edn article contains the same iSuppli data only they fleshed the table out to include annual stats as well:
http://www.edn.com/article/CA6663913.html
Taking the 2008 annual data and ranking by revenue we get:
Rank.......Company.......Total 2008 revenue
..1.............TSMC.............$10,253
..2..............UMC..............$2,939
..3..........Chartered..........$1,778
..4.............SMIC..............$1,354
..5..........Vanguard...........$515
..6........DongbuHi Tek.......$433
..7..............X Fab.............$368
..8............HHNEC.............$367
..9............Tower..............$253
..10...........SSMC.............$176
................Others............$1,405
.................Total.............$19,841
TSMC just dominates the foundry business by revenue, representing more than half the entire market. Adding Globalfoundries to this list will add another $3-4B and put them in 2nd place, but almost 100% of that revenue will be AMD on 45nm SOI so it wouldn't really be much value to add them to the comparison here.
