I would expect that all major gaming companies will begin offering 9800-series mice very soon as the swap should be relatively uncomplicated.
And yes 8200 DPI is approximately 5000 DPI more than anyone needs.
I do know, hence that note, that most manufacturers didnt manage to use Avago 9500 properly. Logitech managed that better than most. Its still not that good as old DeathAdder accuracy, but I kinda dont expect to see anything like that every again.
Its usable for gaming, which other variants of Avago 9500 are not.
I kinda doubt newer 9800 will be better, but I will try it eventually. 8200 DPI is really too much. Those 5000 are usable, but frankly nothing over 3000 is much usefull.
Its like megapixels in compact cameras.. you have more of them, so you have that ugly noisy photo in bigger size (that doesnt include dSLRs ofc. just point-n-shoots).
