I get a bunch of questions daily about the S6 IS, the source I originally quoted said there would be announcement in June. He was right about the announcement (Rebel XS & 430EX II), just not about which camera(s).
I know a lot of you are ready to rush out and buy one, it will be a solid upgrade.
To refresh, here's the specs quoted:
I received new info about possible video resolution and the DIGIC III.
Proc: DIGIC III
Zoom: 15x (28-420)
Flash shoe: Yes
Battery: Dedicated Li-Ion
Screen: 2.5″ articulating
Body: Rubberized gripping & lighter weight
Ergonomics: Jog wheel introduced
Image Type: RAW & Jpeg
I'm going with an August announcement and them starting to trickle out soon after.
