I'm looking forward to 7.2, despite any real need for an image gallery (personally)...
The image gallery looks cool, but we cannot afford it. Just on text with a bit of graphics we eat away about 80gb's of traffic a month. If we would host the images also that people put in their posts we would be well over a few terrabyte a month.
But there's more stuff in UBB we don't use, so no problemo and looking forward to 7.2 too.
