Yes this is true but networks as well as Sony have already stated that they will not adopt this new format as it will require too much cost and will require more upgrading There simply is no need to go higher than 1080p.1440P is on the horizon .... I've already seen it at our industry conventions (Cedia). A few issues they need to work out first (like HDMI can't handle it yet) before it arrives on the consumer market.
They were shooting for a mid 2011 release of the resolution standard.
