Socket 1366 Heatsinks in the Frostytech Labs

The first Intel socket LGA1366 heatsinks have landed in the Frostytech labs from a well known heatsink company whose name we can't mention, and we expect to have a full collection of LGA1366 heastink reviews shortly. In the mean time, answers to questions like: 1). Will current Intel socket 775 heatsinks fit on Intel socket 1366 motherboards? 3). Do Nehalem socket 1366 heatsinks use the plastic push pin clips, or something new? 2). If I use a socket 775-to-1366 adaptor bracket to make my existing Intel heatsink fit onto a Socket 1366 motherboard, is that okay?
