Bitmain have never said that it will be possible to upgrade the S1 so not sure why so many people think it will be.

Actually......

Reserved for Q&A

1. Will there be upgrade parts for S1 and S2?

Yes, there will be. But we still need to solve some production/testing problem before we finalize the plan and public it.

I stand corrected, had never seen them mention it only the S2

here is another recent quote

ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382

Published on June 18th, 2014,

Next Generation of ANTMINER Product: S3

S3 is a blade style miner similar with S1, and two S3 hash blades share one control board.
Each ANTMINER S3 contains 32 BM1382 chips. It will be hashing at 504 GH/s while consumes about 390W from the wall. The overall efficiency is about 0.77 J/GH.
The design of heat sink is customized but it is compatible with the hashing board of S1. Hence we will be able to provide all the S1 buyers an option of upgrade.
We have added a box over S3 to control the air flow, and we use two fans so that each fan will be able to work at lower speed.

so its better to wait for S3 than buying S2? i have two S1 right now. thx!
