That's not good news. I'm looking at one of these Pioneers for next go round with blu-ray players. This makes doing so problematic. The specs read like this can be addressed given its memory buffer.

Seems to be as reported by owners. Pause is longer than what we are used to. Long enough as just posted to impact viewing pleasure.
"Smooth layer changes have been a nagging issue from the beginning of DVD."
Not sure I agree with such a general statement. My lowly Pioneer 410 had little to no observable layer breaks. Same with my Pioneer DV-610. Now that I think about it I don't remember seeing one on the latest handful of sd-dvd's I watched on it.
"The Blu-ray memory spec has nothing to do with DVD layer change."
I believe we are aware of that.
From your post, it sounded like you were saying that even though the firmware update wasn't fixing the layer change, that the the player's memory buffer could somehow be used to reduce the problem.
Again, smooth layer breaks have indeed been a problem for DVDs, and certainly for early titles. Professional authoring software tools from Toshiba, Panasonic, Daikin and Sonic did not have this perfected at first, and pilot error, both authoring and mastering, compounded the problem of making smooth switches. Most early Hollywood titles were single-layer discs simply because by keeping the bit rates relatively confined, the entire movie could be put on one layer, so dual layer issue didn't arise. As higher bit rate special edition titles and longer movies were put on DVD, layer change became important, but took awhile to get it down right. Mostly depends on the specific disc. Placement of the break is crucial. I've seen titles that apparently due to layout reasons, are forced to make the layer change right in the middle of a shot. That's a sure formula to be noticed. Doing it at a cut is obviously going to be less intrusive, and if there's a fade to black or flying into a black hole, or the break is placed in the midst of a jerking action sequence, the break can be obscured more easily.
I've never had particular issues on my various Pioneer machines: 500, 363, 440, 520, 656, 7200 and LX1.
I haven't seen the 320 problem first hand, but it there really is a 2-3 second delay for what should be a normal playback layer change, Pioneer shouldn't have even let those players out the door.
