Not sure that XLR is essential, although many like them . . . the problem is there are only two (I understand, L+R), so it's difficult to mic-up any event and then mix it Post.
Really useful features IMHO are LANC (remote control whilst filming on a dolly, for example, - and Vid-out when you are one of a 3-camera shoot.
Have you any test shots from that lens?
I like the dual SDHC card feature on some Canons . . . other MFrs are trying to shift away from cheap SDHC memory - so they can rip us off with funny cards.
+It's not a new-model, so there may be something "better" about to hit the shops!
-JVC were showing 4K camcorders recently . . . and this is probably where video is going, now that many folk have big screens. True most are HD at best, but the next thing will be "super HD" - and that probably means 4K.
Let us know what yu find . . .
