That article doesn't do a very good job explaining the upgrade kit. It states that the upgraded S2 will be able to hash at the same speed and power consumption as the S5.... which would mean the upgrade kit would offer a whole 150GH/s over the S2. Also, the S2 has slots for 10 boards - which are originally filled with what are essentially underclocked S1 boards. If the article is to be believed, then what are the other 8 slots going to be used for, if anything?
I'll wait until something official from Bitmain actually appears instead of treating the linked article as any kind of source of truth, because that article smacks of just as much speculation as this thread
.
The article smacks of someone who doesn't actually know hardware attempting to write a qualitative piece about some hardware and doing a bad job with the details. Bitmain's given more info, still not a lot but enough to refine some of the speculation. At least we have the hardware config, and can use that to estimate specs. It looks to be pretty decent, as long as it's also not stupid expensive.
