Exists, but not ready for production yet
The GT218 chip, Nvidia's entry level 40nm GPU, is still not ready for final graphics card production.
The chips might be finalized shortly, and TSMC should start printing them soon, but Nvidia still has to ship the chips to its partners and get first cards out. We heard that April is the earliest timeframe in which you should expect these cards out, and we can only have our fingers crossed for Nvidia and hope that they can meet their own schedule.
This is a huge step for Nvidia, as 40nm is not an optical shrink, it is a brand new process and it is always complicated to move from 65nm full node to 40nm full node. Bear in mind that 55nm was only an optical shrink, half node process.
