You failed to mention that Resident Evil 2 sold around 4.96 million copies (please cite your sources) when it was released on the original Playstation in 1998, with no other release on a major platform until a year later (and even then it was only the PC). It was not until almost a good 2 years later that it was released for the N64 and Dreamcast. In the case of Resident Evil 5, it is being released simultaneously on two systems, each with an install base smaller than the original Playstation had when Resident Evil 2 was released.
If you look at Capcom's site, you notice that sales of Resident Evil games peaked with Resident Evil 2 and have declined since. Resident Evil 2 sold 4.96 million copies; Resident Evil 3 sold 3.5 million copies; Resident Evil 4 sold 3.6 million copies(Gamecube + PS2 numbers) and all of the rest of the Resident Evil releases since Resident Evil 2's have sold sub-1.4 million copies . For Resident Evil 4 the Wii number is not included since this game will not be released on the Wii or another major platform, so adding in sales for a third platform skews the numbers as we are predicting sales based on Resident Evil 5 which will be released on two platforms.
Due to this, the possibility of Resident Evil 5 selling nearly 5 million combined copies seems unlikely, though not implausibly. It would make Resident Evil 5 the second best selling Capcom game of all time. We are currently predicting for this stock alone, just the Xbox360 version, to be their 4th best selling game of all time, which seems highly unlikely. Take into account the fact that this will be released on both the PS3 and Xbox360, each of their GLS should be sub-3 million since they would end up sharing total sales.
From this we can take the maximum a Resident Evil game as sold (4.96 million from Resident Evil 2) and cut that in half to reach the GLS of each Resident Evil 5 stock, which would be around 2.5 million. Though Devil May Cry shipped around 2 million copies in a short period of time, I expect sales to be front loaded, so it would level out around 3-3.5 million eventually. It is doubtful that Resident Evil 5 will ship nearly 4.7 million in its first couple months, a number around 2.5 million combined (for both Xbox360 and PS3) seems more plausible. Due to this I think a lifetime total of around 5 million for Xbox360 and PS3 combined is likely, and due to the previous ratio breakdown, GLS for the Xbox360 version of Resident Evil 5 should be around 2.5 million.

Looking at the most recent NPD numbers has the Devil May Cry 4 breakdown between the PS3 and Xbox360 at about a 45:55 ratio. vgchartz currently has Devil May Cry 4 on the PS3 selling more copies worldwide, but that ratio has to be taken with a grain of salt. Though, due to the fact that the PS3 is outselling the Xbox360 in Japan, that seems plausible. Due to this, a 50:50 ratio in the future for Resident Evil 5 game sales seems likely.
