Do you know for sure they're not EVER going to address the issue? I mean the games been out what a week? And I can't comment on the HDTV lag, but i highly doubt its that intense/unadjustable. With my plain old tv it works just fine with no lag and I'm not button mashing... just saying...
I'm sorry, but i'm not big on the idea of the internet being a competitive situation. I'd think more toward arcade/tournaments for a competitive appeal not online which is always subject to lag no matter how beautiful your connection is. Grant it it is competition, its not the end all be all for competitive players.
And personally I've ran into several people who have pulled off long ass real combos/juggles just fine on the ranked and player matches. I've found great competition actually, with the occasional button masher who was pretty easy to stomp out unless severe lag hit which is always the case when you hit lag, it just becomes hard to respond. But for the most part in a good connection for me if it had lag it was you staring at the sweet combo and your braining lagging in reaction.
But its your opinion that's just my two cents
