With the uncertainty about HDDVD and blu ray would it be better to upgrade to the Onkyo 875 rather that the 605 or 705? My thought being the 875 has up scaling built in therefore regardless of who wins the format war I would not be restricted or limited to a manufacture. Basically what I am edging at is the 875 would upscale HDDVD and play the blue ray anyway. Or do all blue rays have built in upscalers? I have read on here the 705 is better than the 605 for music how does the 875 compare.
