Same here. I’ve been reading about people flashing back to stock in order to checkout the update, but I will not do it. I do not know specifically what the differences will be, but I already have froyo via custom ROM and have no interest in rerooting, eliminating bloatware, re-customizing, etc. when I ultimately decide (again) that a custom ROM is what I desire. Rooting and flashing a custom ROM offers maximum customization and developers are very good about filling in gaps (features and utilities) left by stock.
