It may have been a month, or so since my last visit, but has it really changed that much, or are you referring to the oven bit they added with the update they had in the early 90's, which was almost 30 years ago. The ride originally used to be updated a minimum of once a decade and now looks dated and has all the technology that we have today. It's the future, not the present. We may have a nostalgic kick lately, but last time I checked, I don't get Christmas presents in the form of those shoes daughter received and no one has a car phone anymore.
If they don't want to go all out and really try to aim for far into the future as it's intended to be, they could at least replace a few props, and change the dialogue a little bit to be in the now, or at least a little into the future.
