This may not be popular to say but the new SL1 will definitely get my attention once:
1.) the price drops significantly AND
2.) if Canon releases a couple more pancakes (20'ish mm & a 30'ish mm) at a reasonable price.
Totally with you on that. Aside from professional gigs I love taking my 5DIII and 40mm out to social occasions because it feels like a compact to me. However, the SL1 with a series of pancakes as you mentioned above would be bliss for such occasions.
Agree, a wide pancake on this could make for a nice street setup. Would be nice to see a EF-S pancake unless they are going to make a really wide EF one.
I asked about a 20mm pancake a while back and aparently it's not viable
