Read my post on HDMI before you buy. The existing standard 1.2 and forthcoming standards 1.3 are looking to squeeze more data through what is basically a set of twisted pair data cables with no error correction. The higher data rates will 'stress' the vulnerabilities of the cable standard, and will not address its fundamental flaws. The telecommunications industry has been able to increase data rates over standard copper cable for many years now (e.g. high bandwidth ADSL over copper telephone twisted pairs), but this has been achieved by better protocols and error correction at both ends. Much depends on the length and the 'route' that the cable takes. Put a 90 bend in the wire (if you can) and this causes skin effects more pronounced than that produced by a cable just transmitting analogue signals and hence causes data loss and timing errors. To achieve the higher data rates, some manufacturers are already producing insulation as thick as the cables that you see BT digging up in the roads. Try routing that in today's modern WAF household. When data packets arrive at different times due to minute differences in cable length (a bit like being on the outside of a race track as opposed to the inside), there is no buffering or retiming at the projector end (now there is a good idea). Hence you may need to buy a repeater. More money spent in order to satisfy copyright protection (HDCP) requirements. What a money making industry this is!
