At present, Microsoft (Research) says the HD-DVD will only be for movies. There are no current plans to offer games on HD-DVDs.
That could – and very likely will - change, of course. As developers begin to truly take advantage of the system's features in the coming months and years, you're going to see games that cannot fit onto a single DVD. In fact, that's already happening. The developer of "Enchant Arms," an upcoming role-playing game in Japan, told Gamespot.com last year it was hoping to be able to fit the game on two discs, but admitted "that's even looking grim." Any old school gamer can tell you that switching discs while playing is not a fun experience.
Game developers are in something of a bind, though. Even if Microsoft opens up the HD-DVD player for game software and even if sales of the peripheral soar, game makers will still have to publish two versions of the game, which could confuse and frustrate consumers.
É uma política inicial da M$, mas acredito certamente, como podes ver neste artigo, que quando começarem a sair jogos maiores que um DVD, essa mesma política mude. Não é tecnicamente impossível, e sinceramente, até acredito q dentro de alguns meses, lá para o verão do ano que vem, saiam os primeiros jogos em HD-DVD. Provavelmente, de inicio, a edição do jogo será em ambos os formatos...
Acho que esta estratégia da M$ serve principalmente para quem compre agora a consola com DVD, n fike a pensar q vai ter de gastar maos $200 para dps conseguir jogar aos novos jogos, por isso preferem dizer que para já é para ver filmes. Se fores a ver, o mesmo se passou nos PCs, aquando dos leitores de DVD, os jogos sairam em ambos os formatos.
Em relação ao VC-1, é certo que ambos os formatos o suportam, mas o mais giro foi os blu-ray terem saído em MPEG2 inicialmente...

Summary:
HD image quality is by and large dictated by its bit-rate, MPEG2 is an ancient (in relative terms) video codec. VC-1 is two to three times more efficient than MPEG2, and thus far it seems to be apparent, that Blu-ray’s smaller disc sizes are only exacerbating this inefficiency.
Until Blu-ray either adopts VC-1 as their sole video codec or releases Blu-ray movies on 50GB discs, it’s very unlikely that Blu-ray’s image quality will even match, much less surpass that of HD-DVD’s.
HD-DVD is simply delivering higher bit-rates and overall better image quality, than Blu-ray is capable of with the combination of MPEG2 and 25GB Blu-ray discs.
In theory with 50GB discs Blu-ray could greatly improve its video quality even with MPEG2, but again until it’s on shelves and in players it’s just a theory.
Like I stated earlier, much of this could change with the introduction of dual-layer, 25GB (50GB total) discs from Blu-ray. But this begs the question if Blu-ray part deux only matches and doesn’t surpass HD-DVD in video quality, why the $500 premium?
Com um leitor em condições e já os há, de várias marcas, os resultados são substancialmente diferentes.
