Just curious if anyone remembered when the new "model year" came out on these. DD is hanging tight at 39lbs in her XT, but I'd really like to see the new covers before I buy an XTSL. I emailed Russ a few months ago, and he said there will be no higher weight limit or adjusted boot, so it's just a matter of patterns, I believe. I didn't think to ask when they'd be coming out. I just know they came out shortly after I bought this XT in July last year. Does anyone remember?
