Looking forward to this announcement, although I don't know if/when I would be able to afford it. I already bought 2 of the 3 RF lenses I have at the beginning of the year, and prices have gone up since then. Not to mention the USDJPY exchange rate is absolutely ridiculous right now, so putting off big purchases for a good while. I'm hoping it's a 1.2, and I'm betting it will be about $2700 like the 85mm. $2500 or lower, and I would definitely consider picking it up by next summer.
(Btw, is this rumor post by the actual Canon Rumors (And Information) Guy, or one of the new mods?)
