I was thinking the same thing. Just wanted some confirmation it's still coming because I'm trying to figure out to sell them now and buy s4's or wait for the upgrade
Exactly!
S1 have upgrades-but are they worth it?
Selling S2 was probably best done before the announcement.
S2s are heavy. 1 TH/s also isn't very much anymore. Would be hard to sell for anything significant IMHO.

S2 mines .25 btc now
Over what time period?
Lifetime. Actually about .3 btc
at 15% difficulty rise every adjustment period and .16 cents electricity kw/hr
Yes they are a huge loss as they came out at the wrong time just before the s3, I feel sorry for people asking for $1000 on ebay
